97 GTP ECM wire harnes

[Mrroddavis2]

I am splicing in an blue side ECM harness but whats messing me up is some of the wires have 2 - 3 of the same color wires, how can you figure out which wire go to which pin on the ecm harness there are multiple of 2 or 3 wires of the same color on that blue connector and no way to tell the difference between them!

Can anybody tell me a way to figure this out?

Did you cut them all off before labeling each one with pin number? If so Yikes.

Im not sure if a wire diagram would help.

Maybe someone else has a fix for you but I dont think its looking good my friend

Nope I did not label them so I am screwed

I went and looked at mine. I didnt take it apart IIRC the blue one is the bottom of the pcm

Just by looking I seen 2 green wires and one has a white stripe on it also, there are 2 banks of wires that feed into the one harness so maybe you can use a process of elimination to right this ship.

Thats what I have been trying all day on that blue side of the harness there are 2 blue wires with black stripes, 2 yellow wires, 3 drk green with white lines, 2 red with black line, 2 solid gray and 2 solid purple on 1 side of the harness so I been switching between them earlier today.
Right now when I turn the car on it idle real high, you can hear the air being sucked into the intake cause its really loud when I shift into drive or reverse the trans hits into gear really hard you can hear it and the boost gauge is missing from the info center on the dash.
I am not sure if some of these issues is because of the zzp ECM i am trying out I might put back in my original ecm and figure out what wires go with what while using the OEM ECM
I matched up all other wires on the harness just not sure on the ones that have 2-3 of the same color so I swithed back and fourth some of those wires a couple of times

Thanks for the pics I just could not get the pic for wires 28-52 But I finally got her running right yesterday still not sure on 2-4 of those wires and the 3 green and white ones cause 1 wire out the 3 suppose to be for the EGR and the other 2 are just for the AC but she is running I might have to go visit ZZP to get a case learn for the ECM I got from them cause the check engine light is on but they say 97 dont need it
