Anyone that drives a '95 thinking about installing a megasquirt be careful, because all the wiring diagrams i have (chiltons) and have found online (95 NT PCM Pinout) are completely incorrect. I just spent few hours tracing wires and doing continuity checks from sensors to the PCM pins to verify each connection that I was tapping, but finally have my megasquirt reading all required sensor data. When I complete my installation, I will do a write-up on the pin # and wire color, since both seemed to be incorrect in almost all cases, but the good news is I have all the inputs coming in correctly now.

The info for the pin out on the 95's and other years are here on this site. http://www.2gnt.com/nuke/modules.php?name=Sections&op=viewarticle&artid=64

I have installed the MSnS on my 95, so if you have any questions let me know and I will try to help you out.

That diagram is from a chilton isnt it? Dino and I discussed this a while back and noticed the schematics in the entire manual have details wrong with them. never go by chilton diagrams period!

The link you provided has the exact same incorrect wiring :). Example, pin 14 on my car definetly is NOT a black/white wire and does not have any voltage coming out of it while the ignition is turned to run. Like I said, all references I've found have been incorrect. Thank you for trying though.

Then your car is different, because those are perfectly correct on *MY* 95.

I've always said, go by color, because the pinouts are almost always wrong in all cases for all 2gnts, but the colors are always the same.

TPS signal is always brown / red stripe
ECU power is always back / white stripe.
Fuel pump is always white / red stripe
tach is always solid white
CrPS is always blue / white
etc, etc, etc.

If the colors were completely wrong and our diagrams were completely wrong, why is it that no one has noticed except you?

That is weird, but the colors were also wrong, so no good. I wonder why mine is different and yours isn't... it's the 60 pin connector, and i've got a '95 eagle talon 420a :). Colors were right on about 2 of the 6-7 wires I connected, and the pins were not correct once.

Yep, you've got a freak car. Those pin-outs are dead on for my '95 Eagle Talon ESI. If you compile a complete list of all 60 pins with base wire color and stripes, I can add it to our information.

Now with more power and fewer leaks



Gimme fuel...Gimme fire...Gimme that which I desire

Im also running squirt on my 95. I ignored the pin out entirely and went by color alone. Works like a charm for all except the FP relay, for that I have the rewire done and went straight to it by passing the factory relay entirely. If you have any problems you can contact me.

Alright, will do. I will compile a list of as many pins as I can, but I really don't feel like tracing pins that I don't need to use ;). I will however let you know all the pins and colors that I used for my megasquirt installation.

If you have an early 95 ATX, then most of the colors may be different and the pinouts will be completely wrong. I have one sitting here and it uses perhaps 1/3 of the pins in the 60-pin connector, whereas most later 95's use more than half. The early 95's are a strange lot.

You have an early '95 model ecu (2gnt's manufactured before may '95 I believe, I think the ecu has a '94 manufacture date on it).

I have pinouts for this. Email me (edit: baldrjo@auburn.edu), and I'll reply back w/ them attached.

Dino, do you want to host them, or do you think it would cause too much confusion.

god dammit x(

yes please post the diagram someplace... i hafta check my exact date but i'm almost sure i'm one've those. i've got the old '94 drum brakes as well. finding the parts for those was such a bitch when i didn't know they changed mid-year.

whyyyyy mitsu???? why why why why???? :wallbash

oh well thanks for bringing up this issue. prolly save me a lot of headaches in the near future. :thumbsup

I have an early model MTX, but yes, the pinouts and colors are very wrong :). Wasn't to difficult to trace them, just a lot of extra time/effort and a bit of confusion when first starting. I've got all my wiring done for the fuel side of things, and only a few things left for ignition, but a correct wiring diagram would be great to have so I can make sure I didn't tap something from the wrong spot :).

What colors were you seeing? I'm curious.

bump

where'd you go dude? another 95 freak here lookin for some info :P

From what i'm seeing on the early 95 pinouts WickedESi sent me, the locations are different but once again, the colors are the same. I'm confused.
