Hey all, I'm currently working on mapping out the 98-99 DCC pin out so I could convert my 91-97 harness. I checked out the factory service manual for both a 98 and 99 vr-4 and I've come up with this chart

Yes I have to move some of the pins if indeed my chart is 100% correct



I've also bench tested some of the connectors and it seems the chart is somewhat accurate so far. Any further information will be posted here.

It's cool to finally see the 99 unit in action. Keep up the good work. Personally after seeing it, I think I think I actually like the looks of the older style display better. It's just more colorful.

Does the new unit not require that extra controller box?

Thanks! Correct, the newer units don't require the computer, its all self contained

Thanks found one off of ebay. I decided to take a different approach. I'm going to use a diamante DCC and swap the guts into the 98-99 DCC. The diamante has an internal temperature, has a pin out for the rear defroster (could delete the defroster and ecs switch), has a blue screen (matches my car) and the wiring is much more simple. Stay tuned

Hmm...just checking this thread out, looking at that map out of the wiring and now I've got a question. I see water temp sensor in there. What's this for? I'm remembering a water temp sensor for a/c, I'm assuming that's what it's for? Reason I'm asking is I deleted all a/c years ago and recently removed that sensor and I've noticed the air isn't as hot while at idle now vs. while driving. Not sure if that's coincidental or not and that map out brought on curiosity that it may do more than just a/c?

Tensecs2fame

Water temp sensor controls how much heat from the radiator fluid hits the heater core. It'll have a direct impact on how much heat you get

Interesting! So, by removing that, I DID change heat output then, correct? Is there anything on how this works exactly? It still puts out blistering heat like before, but only while driving, since the RPMs are higher than at idle.

I thought that was just for a/c so I removed it, less wiring and crap. I did a mild wire tuck, this last go around in the engine bay.

Great work everyone!!

Considering how cheap the Diamante DCC's are this is a great option. Ebay has used ones listed as low as $30.00.

Couple Questions?

1. The Diamante one replaces the computer in the center console "Long thin black box" or the one under the Pass kick panel?

2. Is the only major difference in the cases the mounting tabs? if so I could just fab up brackets to use the diamante case considering how rare the 99 ones are.

Seeing as Shooter posted the wiring I'm going to pick up a diamante one for $30 and see what I can d about making a harness based off your answers. I hate the current 3S DCC. they break to easily and cost a small fortune to replace. When the blow they are pretty much dead and need to be replaced anyway. I would rather that be a $30 part then a couple hundred...

I stumbled across Shooters video I'll add to this also:

The mounting tabs are different, the wiring is different, you'll need diamante male connectors and 3000gt female connectors and you can make an adapter harness. You'll still need to map out the 3000gt side of the connection as that hasn't been done yet. I've confirmed many of the wires match in color while a few are different, however if any of the wires are done incorrectly you can burn out a sensor or module. I won't be able to get to that for a while since I don't have my car readily available

So I went through the wiring this morning as I am bored at work...lol. So the diamante unit will replace the display, black control unit under the display and the lock controller box located under the passenger side foot panel. I got about 90% of things mapped out but others just don't make sense to me and a lot of stuff is missing.

Here is what I have found control wise missing in the Diamante wiring that exists in the 3S wiring.

AIR CONDITIONING COMPRESSOR LOCK CONTROLLER FUNCTIONS
condensor fan motor relay - will not turn on the fan
http://3s.gonzoinc.com/albums/userpics/10002/condensorFan.JPG

it also controls the clutch being engaged
http://3s.gonzoinc.com/albums/userpics/10002/compClutch.JPG

Damper control is missing some inputs as the position sensors are all three wires but the Diamante control only list 2
http://3s.gonzoinc.com/albums/userpics/10002/mode_dampeners_position.JPG

Fan motor and transistor don't really match up either. I am assuming 51-52 match up to pins 1-2 but I don't know which is which...
http://3s.gonzoinc.com/albums/userpics/10002/Blower-Power_transistor.JPG


Here is the wiring as I have it mapped out now. Someone please go over this to double check the work. The wiring is color coded to represent the unit the wires come out of. Most of the wiring is contained to the A/C control unit.
I upload to Google docs so you can see it better, it's view only permissions though so it doesn't get messed up:

01-23-2014, 11:39 AM
So looking a little closed at Tensecs2fame wiring I was able to figure out the rest of the Blend Air Position controls and updated the Google doc.

I also found out that the lock controller control both the fans and the clutch. I was assuming this was two different circuits but then realized the two diagrams connect.... DUH So that means that the pin 13 "REFRIGERANT TEMP SENSOR" is actually what controls the clutch and fan relay circuit... So that has been updated also.

So the last Item I have is the "DUAL HI-LOW SWITCH" which I believe connects to the blower motor relay pin 101 on the control unit. Seeing as the rest of the unit is +12V I would need someone to confirm that pin 101 on the 3S unit or pin 36 G-W is a grounded switch. My unit is not in yet so I can't test it myself just yet. Considering this seems to be the last thing on the list and everything else is connected, this should be the right one...

DrGonzo
01-23-2014, 04:28 PM
So on my lunch break I swung by the junk yard and got a unit and the wiring harness for it. I really just needed the harness as I ordered a unit from ebay. Either way they were the same price and I have one to test with and another to install. The one I got came out of a 2001 and I noticed for the most part the wiring is correct, except for a few things.

It looks like the 2000+ did not have the A/C compressor safety where it would shut off the A/C if it saw the belt slipping. This was to save the car as if the compressor locked up it would break the belt. Looking over the circuit the functionality is still there I just need to add in more wires for it. I may just use it without as the last two times my compressor went out it was squealing like a bitch so that is enough safety for me...LOL

it also looks like this unit has a built in interior temp sensor. I took it apart to clean it and the sensor is mounted right on the front of the unit.

I also have two other wires W-R at pin 12 and G-O at pin 34. I am assuming these are for the defrost and outside temp. Should be easy to figure out.

Tensecs2fame
01-23-2014, 05:02 PM
Seems like you're on the right path. I have a link to a manufacturer that can replicate the diamante connectors that I'll send to you later. They may or may not make the 3000gt side too. I don't have easy access to my car so I can't confirm that. Just hook me up with a harness ;)

Tensecs2fame
01-23-2014, 05:04 PM
Keep in mind the initial chart I posted is for a 1998-1999 digital climate control and may be different to a diamante harness

DrGonzo
01-23-2014, 05:22 PM
Considering most of the wiring colors match up with the stealth ones in the same spots I don't think they changed throughout the years besides removing the compressor check and the two extra wires.

I got mine to power up and illuminate. the bulbs for the screen are out so I have to go get new ones. the screen works if I shine a light in the holes...LOL

I'm having a hard time tracking down a diamante manual so if anyone has one please let me know.

What I also found that is interesting is that the connectors for the diamante control are the same as the ones for the 3S control unit under the display. for the mast part they contain the same wires minus a couple small changes. it may be possible to just re-pin the stock one to work with the diamante one...

I have a diamante manual I'll send you when I'm home too

DrGonzo
01-24-2014, 10:28 AM
So I looked over the wiring diagrams that you sent and everything looks to be the same minus one main thing. Pin 10 is a 5v shared lead to multiple different sensors, thermo, water, outside temp and both potentiometers share this 5v lead. Looking at the 3s diagram, they don't share a common 5v pin. The 5v goes into the blend air damper. the air inlet sensor shares a line from the interior sensor which is built into the Diamante unit and the air thermo sensor shares a line off the mode selection damper. So some wiring will have to be modified through out the car also. Once I figure out where all of the wiring lives in the car I can figure out how to share the lines. Basically what I need to do is splice the 5v going into the blend air damper, into the air thermo and air inlet sensors so they all have a common 5v into pin 10

Uh...we do? Never seen any kind of a valve between the core and the engine. I do have a first gen though.

DrGonzo
01-24-2014, 01:20 PM
That would be a sensor not a valve. Also known as the AC switch. Not sure why the AC system need to know what the coolant temp is. My assumption is it controls how far to open the damper when the heat is on.

DrGonzo
01-24-2014, 01:55 PM
So I looked over the mechanical manual looking for this damn coolant sensor. It is behind the glovebox and I guess connects to the heater core or something:

http://3s.gonzoinc.com/albums/userpics/10002/engineCoolantTempSensor.png

interesting enough, the mechanical manual shows the different sensors I talked about earlier do in fact share a common 5v

http://3s.gonzoinc.com/albums/userpics/10002/SensorsCommonPower.png


So when I get time and it warms up some, I'll have to test out these connections to ensure they do share the same common power as this will make things much easier to do the swap.

I'm saying I don't think there is anything that changes the flow of coolant from the engine/radiator to the heater core under the dash. Makes sense that something is used to change how much air flows across the core. No sense blowing cold air around the cabin if the core is -10degrees.

Nihil
01-24-2014, 05:36 PM
Yeah, I thought it was for controlling the fans, but maybe that's on 2g's?

The only thing I could think of is it does something with a blending door, but it still doesn't make sense that I removed sensor and the heat changes with engine RPM. I've gotta do some more wiring, alarm install and stuff so I'll add that sensor back to my car and see what happens.

on topic, this is awesome progress, I'd love to install a newer, simpler more reliable DCC into my cars!

01-24-2014, 05:47 PM
The main thing with this though id that the Diamante unit will not fit into the stock 3S slot as it is completely different. i am going to take Shooter's route and hack up a manual A/C control and mount the Diamante unit in it. that way it will mount like stock and the Manual uits are easy to get and cheap.

No much to update on really. i was able to get a manual A/C control unit from the junk yard. I gutted it and cut the face out to mount the Diamante control unit in since that one will not directly mount in the car.

I'll be using plastic glue to weld the 2 pieces together and form the two pieces. This will take some time due to having to wait for the plastic glue to cure fully before I can sand it. I am glad that I bought two units as I broke a couple of the buttons getting them off of the first unit. I was able to salvage them all on the second unit once I knew how it all came apart...:p

So, I've got some questions about this, guys!

First, any new progress?

Second, with as much as has been mapped out and figured out, is all the functionality there to work JUST the heat side of things, I've got anything and EVERYTHING A/C wise totally removed.

Thirdly, I'm currently doing an alarm install and I'm wondering about my aux channel outputs from the alarm being able to power my DCC, I believe they're 200ma outputs for triggering relays, but I'm wondering if it's possible to trigger the wires, using factory relay/wiring, enabling essentially full function of the DCC? They're momentary (validity) meaning as long as I'm sending signal, it'll power, so I could wire an aux to the fan to turn up with each press, if possible and same with heat.

I've got a lot of aux channels so I'm just curious.

No new progress. I have my house packed up right now as it's on the market, so I won't pick the project back up until the current house sells and I'm in a new one.


I have things mapped out to the stock 3S wiring so you just need to tap into the wiring harness for the black box behind the DCC. I'm hoping to find some male connector ends so I can just make a harness out of it. That's down the road though.

My wiring diagram is accurate. I still need to finish off the bezel piece so I can mount it. I should have that completed in the next couple weeks

The only thing is I can't check the A/C operation right now as I need to change out my compressor. I don't see a reason for it to now work as everything else is working as it should.

I couldn't track down female plugs for the 3S AC computer so I just T'd into the main lines and soldered the connections. So I have both the stock and Diamante plugs installed. I only had to make one extension wire "The blue wires" to run up to the plug for the AC display. Those wires are for the illumination and dimmer controls.

Technically this entire thread is the Guide...


I was able to get the car started today after fixing my ECU wiring issue. I did conform that the AC compressor does come on as it should. So it looks like the Diamante unit uses separate wires for the Tamp sensor and the High/Low pressure switches as where the 3S one uses a single wire and the sensors are in tandem.

I'm working on the face plate now. Earlier you saw how I used a manaul A/C plate, gutted it and mounted the diamante plate with epoxy. well I needed to fill it all in and make it smooth. Epoxy putty works great for this! Pull off a piece, roll it up into a log and apply. Once dried I sanded and shaped it.

http://3s.gonzoinc.com/albums/userpics/10002/IMG_1545.JPG


One coat of primer, then sand and repeat until I get a nice smooth surface. I'll then hit it with a low gloss black paint and satin clear.

That's awesome, dude!

So, what gets eliminated in this conversion? The box behind the dash as well? Is there an a/c fuse block on the passenger side kick as well? I can't remember what all is hangin around for the DCC stuff.

DrGonzo
07-01-2014, 08:57 AM
The black box behind the radio and the black box attached the passenger side foot panel plastic both get eliminated. the box behind the radio is actually the brain of the system. The display is just that, nothing more than a display that feeds signals to the brain. The box under the passenger plastic is the lock controller. That lock controller gets a signal from the compressor and the tach signal. If it sees the compressor is not rotating fast enough in relation to RPM's, then it shuts off the compressor to safe it from locking up and breaking the belt. My wiring shows how to hook it up but on mine I did not. I have see the compressor revolution sensors go bad on perfectly good compressors which makes them inoperable. By removing the RPM signal it allow the compressor to work again. Usually the compressor makes a god awful noise when it on it's way out so I'll probably always hear it before it locks up.

I'll add that when my compressor failed (housing damaged from over tightening the belt) I ordered a replacement from Rock Auto which I think was the Four Seasons brand. You are supposed to be able to exchanged your manifold from the old to new however the new compressor did not support the RPM sensor as it requires an opening on the casting. I had to improvise to make it work out but came away with the conclusion that there must be manifolds that don't support the RPM signal. I'm just not sure if these manifolds are 3S versions or for other cars because it seems our compressors have multiple applications.

Note, the main issue I ran into with the diamante unit is that the display angle is horrible for the screen. When mounted in the stock 3S location you can barely see the display at a normal angle. If you slouch back in your seat some it gets better. I had a spacer to the top mounting point to angle it back a little to help with the display angle issue. I don't know it this is the same for the 98-99 Displays. I have two different Diamante units and both have the same angle issue.

I don't know it this is the same for the 98-99 Displays. I have two different Diamante units and both have the same angle issue.

Oh I very much agree. at night it isnt too bad but during the day it sucks. Must be angled back about 15 degrees or so.

So is this the finalized wiring conversion chart for this project? It seems to differ in some color codes to the one darksurfr posted, or maybe I was lookin at it wrong.

What years are you guys using from the Diamante?

This wiring chart is the exact one I used and was updated as I was doing my conversion. I did notice the 3S manuals everyone uses does have some differences in the wiring colors. I verified pin count on the plugs and wire tracing.

I think they were 99-03 Diamantes. I got one off of ebay the the other from a pick and pull. I needed to get the second one to compare things and I needed the Diamante plugs and tails. You can find them on ebay but them don't come with plugs:

I'm not sure if there are differences in the wiring on the diamante ones through the years. It is best to go by in count then as those would be the same.

For those trying to do the conversion, I believe that the Diamante CC uses the same type of connector as the Mitsu ECUs. Trying to find matches to this and female connectors for the stock AC stuff to make plug and play harness.

It uses the same connectors as the DCC and AC computer. One is an exact plug in and the other is a little larger. The wiring is different though.

I'm also working on sourcing the plugs to make a conversions harness. You will still need to tap wires in though as the conversion connects at three locations. The A/C Computer, The AC display and the lock controller. It's only 3 wires that need to be run.

the Diamante CC uses smaller connectors. smaller in size in every dimension I believe. I have some right here next to me. They are different in the style of connector too. They dont have the fold lock connector. They have a sheath type that clips in and holds the pins.

Well I know I was able to plug one of the Diamante connectors into the AC computer as that was the first thing I checked.

I got a JDM 98 DCC last time I was in Japan. When I get back home from Japan i'll compare it to the Diamante one I have I think they are the same.

Does any one have pictures of the connectors that are needed? I have a source that might be able to get them. They have been able every connector I have asked for so far. Unfortunately I'm not at home and if I was I would have to take the console apart. If you can get me pictures of the writings on the connectors, the pin count and such I might be able to source them.

Diamante DCC connectors. Don't have any for the 3S DCC o hand since its still packed up.

Found the 3000gt side so I can make plug and play harnesses. I'll search for the diamante side tonight. I have a place to buy them

I'm assuming this excludes the 3 other wires DrGonzo mentioned earlier?

Anyone have a picture of it mounted that shows what everyone means when they say the angle of the display is off?

if you are getting screens from Japan then they are probably angled towards the driver in a RHD car.

That might not be true, I believe how things are angled, has to do with the dash and console moldings, those are specific to LHD and RHD, the components mounted in them are universal fit. That's not to say there aren't variances between JDM, EDM and USDM electronics though, as we know those exist in some of the components, ECU's for example.

Biggest issue is provably the difference in angle from its native home in a Diamante vs the 3S

DocHoliday

My theory: if anyone has done it and can confirm:

On the Diamante it's up high so it's flat screen faces straight out whereas on the 3/S it's down low and has a bubble screen for visibility when you look down at it.

As far as saying they're hard to get. I've picked up 2 in as many weeks. Dirt cheap too.

So it's been a while but figured I would drop a note on this. I have been fighting an issue since I completed my install with the system always blowing hot air. I thought I had a damper stuck open so I was only getting heat. Well I finally figured out that setting the Unit to cool blows hot air and vise versa. So the wiring for what I believe is the Airmix damper is backwards. I have yet to resolve the problem due to many other projects going on. I just dial in the opposite of what I want...LOL

I have also had issues with the A/C not working but I am not sure if it is related to the conversion. My compressor went out some time ago and I think the used one I got is also bad. So I can't make any assumptions to the conversion being a problem at this point.

I am having the exact same issue. Although haven't tried to see if it works backwards.

DrGonzo
12-04-2015, 03:08 PM
Yeah, Mine has been like that since I got it running. Took the dash apart looking for a stuck damper or something and found nothing. Got cold one night and I went to turn it over to heat and BAm, Cold air! LOL That's when I figured out what I had done....LMAO

So I created a wiring harness today (with matching connectors to the factory harness so its plug and play with no cutting of wires) and found a few errors/typos in DrGonzos spreadsheet on google docs.

Edit: Here is a link to a version I edited. All credit goes to Greg (DrGonzo) for the original document.
