center gauges plug pinout

I just put digital water temp, oil pressure, and volt gauges in my center pods, and would like tap into the factory wiring for the water temp and oil pressure, and just replace the factory sending units with my new ones. i did some searching, and only got a partial pin out of the plug, and it wasn't labeled clearly. does anybody know what wire is what?

thanks,
DP

Is my understanding correct, are you trying to use the stock wiring all the way from the plug behind the gauges to the senders?

Correct

Anybody?

narrowed it to what I believe is plug D-09 in the manual.

Pin 1 Black with Yellow stripe - illumination +
Pin 2 Black with White stripe - ignition +
Pin 3 Red with Yellow stripe - coolant temp
Pin 4 Yellow with Red stripe - oil pressure
Pin 5 Black - Ground
Pin 6 No Wire - Empty
Pin 7 Red with Blue stripe - boost gauge
Pin 8 Green with White stripe - variable ground via rheostat



Big Thanks to 2fnloud, and anyonebutme for helping to confirm some wires.

DP once you have this doe will you post back up that it is correct? I want to add the proper notes into my FSM for when I need this info.

Itll be a couple Weeks until I Get
my engine back, but I will keep you updated.

well....that couple of weeks turned into a year and a half, but I can now confirm that all of my gauges are are working properly, and what we have for the pinout is correct.

Pin 8 is that ground for dimmable lights yes?

Pin 1 Black with Yellow stripe - illumination +
Pin 2 Black with White stripe - ignition +
Pin 3 Red with Yellow stripe - coolant temp
Pin 4 Yellow with Red stripe - oil pressure
Pin 5 Black - Ground
Pin 6 No Wire - Empty
Pin 7 Red with Black stripe - boost gauge
Pin 8 Green with White stripe - variable ground via rheostat

I can vouch these are correct..

Yes Steve, Pin eight, wire color remains the same at the panel dimmer switch to the left of the steering wheel.

Not sure why it posted twice..

SWEET, I wrote it out in FSM and put a tab labled gauges.

Never seen this. I can verify it is correct as well.

It is in the manual, but you have to decode the crappy info on the schematic.

Good on you for keeping up with this.
Most people have long forgotten after that much time, lol.

Is it verified as accurate w/logging? I thought you can't use different gauges unless they use the same voltage scale? Interesting since I have a 3 gauge cluster to replace, while my car is still dead.

you have to use the sensors that came with the gauges, this just allows you to use the wires that are already there, and you can't log these as the ECU has it's own sensors to read the information.

I'm trying to wire in some STRI Xlines using as much of the stock wiring as possible. I have a wire that needs to connect to the "LIGHT SWITCH(12VOLT), ILLUMINATION" So is that going to be green/white or black/yellow? If I'm reading this right it would just be black yellow and not be dimmable, correct?

I will look tonight when I get home to see how mine are wired.

I appreciate it. A thread on 3si says that the green/white is the 12v pos for the light and the black with yellow is the ground.

do you want dimmable gauges?

Well I guess if it isn't too inconvenient. I typically understand basic wiring, but this has me sorta stumped.

For non dimmable gauges: Pin 1 Black with Yellow stripe - illumination + and Pin 5 Black - Ground


For dimmable gauges: Pin 1 Black with Yellow stripe - illumination + and Pin 8 Green with White stripe - variable ground via rheostat

the less resistance in the rheostat, the brighter the gauge lights, the more resistance, the dimmer the gauge lights.....get it? You can also test this with a test light or DMM to verify my info.

Sorry to hijack, but to wire something else that is dimmable I would only need to wire into the black w/ yellow stripe? Or would I need to wire into both with the same wire?

See post #24 use only the two wires listed for each option. so for dimmable, use just the: Pin 1 Black with Yellow stripe - illumination + and Pin 8 Green with White stripe - variable ground via rheostat

I used the illumination wire, and it dims when lights come on, but no rheostat action.

Bill what did you ground your gauges to?

Interesting. I don't have a seperate ground available for the lights in the gauges so it looks like I won't be able to use the rheostat.

They are grounded through the factory harness I bwlieve.

Will have to look closer tonight. I have been preoccupied in the engine bay.
