6g74 / built atx

solid shifter bushings installed


brand new mtx starter installed


wish i had more time to clean everything up
this thing was nasty, but the bulk of the gunk is off at least
hopefully next time i do this i'll be dropping in a brand new getrag

So does the electric sensor in the gearbox plug right into the 92< model gearboxes? In the magnas, all years had a cable driven speedo and I'd love to get rid of the cable to clean up the engine bay, but Im guessing it's not possible as then the speedo head would be different aswell?

[n2nsanity]

not that simple, lol

the cable goes straight from the trans into the back of the speedo
i think you'd have to change out the speedo and whole engine wire harness
probably also the dash harness

[n2nsanity]

well, i changed the mtx fluid, 2qts should be enough, it's on jack stands and on a hill, so nowhere near level to check it accurately

dash is back in, kindof, only 2 bolts holding it in case i need to pull it back out

Everything important should be connected for the most part
except for the smaller connector in the dash on the pass side behind the vent, can't find the wire that goes there

and this looks important, drivers side near fuseblock, not sure where it goes

*Edit, found it, the missing end was stuck in between the fender and the body

i thought the clutch safety switch was part of the engine harness, i was wrong....
here's the connector


here's where it would plug into on the mtx dash harness, which i didnt install yet, and hopefully don't have to

test fitted the ebay downpipe today
was pretty tough to get on, don't think the holes were aligned properly
when i take it off again, i'll just widen them a hair
i need to get the o2 bung in anyway
also, it's about 1/2 inch shorter, but i was able to pull the cat forward to get those bolts in, so no big deal

good thing is, plenty of clearance from the oilpan compared to the stock downpipe

[n2nsanity]

Tried a bunch of things today, still no start

First, I found that missing connector, it was stuck behind the fuseblock, in this hollow part of the body
After connecting it and reconnecting the battery, now i hear what sounds like the fuelpump turning on when i try to start, but still nothing from the starter
also, not hearing the click from the mfi relay

Tried the original battery cables, since my current setup is in the trunk and thought maybe bad ground, same results though
battery guage reads 13v and barely fluctuates when i turn the key
seems like it's supposed to drop considerably, even without the starter spinning

I have quite a few ideas to try still, but running out quickly

My remaining suspects:

1st, This is the far end passenger side of the dash, from bottom, behind the ac vent
Can't find the the matching connector anywhere


2nd, does this controller need to be mounted for a good ground? could this be the cause?


3rd, 2 more unidentified connectors, passenger side floorboard where the harness comes in behind fender



other than that, the only other things unplugged are stuff in the dash like ac controls and other dash switches

or maybe somethings not grounded properly, like one of the sensors or relays
there's an mfi relay on pass side of console, its screwed in, but not very tight
there's another relay on drivers side of console, its screwed in, but maybe not tight enough

[TUFFTR]

I would probably bypass it all and wire in your own starter relay. At least then you'll know she'll start.

[n2nsanity]

i've thought about that, maybe the starter relay should be on my list of things to check
right now my $ is on that missing connector on the passenger side up in the dash
i'd suspect the starter relay, but i'm not hearing the normal click from the mfi relay
so i think it's most likely something not plugged in or possibly something wrong with the wire harness although it appears to be in good shape
i'll think twice before i mess with wire harnesses again, lol

Wiring can definitely be a pain in the ass. You might have a pinched wire somewhere that will be hard to find. I hope that's not the case as tracing wires is the most painful job imaginable for any auto work.

As I recall didn't you saw through a harness a while back?
