2G How to replace Wiring harness?

[Meark]

Replacing the front wiring harness to the computer, any help in how to do so would be greatly appreciated.

Un plug all wires, remove harness.



Best answer

I cant get more specific to such a generic question.

It's been done before. Search Google and this site for more info. This thread is for a 1g, but same idea.... http://www.dsmtuners.com/threads/1g-engine-harness-removal.459060/

But chrysler kid is right. Just start unplugging stuff (label plugs and wires if you need to) and take the harness out a little bit at a time. Then reverse the process for the new wiring system.

It's easier with the motor out and the dash removed, but can be done without removing those things.

I feel like I have to pull all of the engine harness to take off the intake manifold anyways.

So start unplugging things starting at the a.c. compressor and work your way back across the motor. After that unplug the alternator and work your way back across the radiator back up to the fuse box. Remove the battery tray and you should see the rubber grommet plug

Inside start at the ecu and follow the wires back up to the firewall

The best way to learn is to just starting pulling it off. Take your time and try not to break any connectors. Luckily 4G harnesses are pretty simple.

Make sure you have the wiring diagrams for your car before you start. Take lots pictures since you won't remember everything.
Make sure the new harness is from the exact same version of the car.

start unplugging everything and labeling plugs, you can depin the plugs if you need to just be sure to remember the orientation

I know this is a couple months old but I’m curious if the interior wire harness differs between M/T and A/T? I have a manual 97 GST and Ive found a automatic 97 gsx donor that is willing to give up the interior harness. Not sure if there are any differences. Thanks for any guidance.
