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.

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.

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.
