2G 95 PCM/ECU reinstall

[spitfiremike]

Ok I was looking around but couldn't find anything that might help me. I am currently replacing the ECU from my 97 GST into a 95 GST. Is there any diagrams or wiring layouts for a 95 Eclipse 4g63t that shows where the wiring leads to on the entire car.

I have a Chiltons book ordered but I need a basic outlook of the entire wiring so I can swap mine. Keep in mind that the engine, wire harness, ECU/PCM, and trans are going to be swapped in later.

The 95s wiring is not so good..

Uh...look under your radio. All you need to do is unplug the stock ECU and plug in the EPROM. It's that easy...

the 97 doesnt have eprom i dont think...
im trying to swap the 97s ecu into the 95
including the wireing..


or do i even have to do that can i just swap the ecu and keep the wiring??

You are correct. The 97's and up do not have EPROMs. However, it's all plug and play. Find your stock ECU and compare the two. You'll find them to be similar and understand what I'm saying.

ya its a little rough.. the accessorie wires running down the middle are bad also idk if i should swap them too..i have the entire car stripped in the inside..

under the dash the other owner had an aftermarket sterio apperently i found that the stock amp under the passenger seat was just cut and not capped.... i was like wtf WTF
and theres a random red wire spliced into engine harness under the dash..? i have no clue what this could be ill prob test it and see if its a power wire.

the fuse box under driver side looks a little funky idk if i should just do the entire cars electric.. lot of work if soo

when you swap a 95 ecu into a 97-99 you need to swap plug wires 1and two with eachother and 3 and 4 with eachother, same goes for the injector connectors,the only way to keep the same ignition, and injector firing order is to get dsmlink with CAS inversion.

I'm putting 97 parts into the 95..

I have some questions about the engine harness..
There is a random red wire spliced under the steering wheel
that runs into the engine harness and is attached to the black and yellow under the dash??
