st205 3sgte wiring into st204 body? - 6G Celicas Forums

Topic #81294 7 posts Started by justincapps94
I'm beginning the swap and I'm not sure what needs to happen as far as wiring goes when I go to install.

So here are my questions:

1: Should I pull both harnesses, and get ahold of someone to wire them together?
or
2: Is is possible to simply cut a hole in the firewall to feed the harness from the 3sgte to the ecu (3sgte ecu of course) and would that work with the rest of the car?


Like I said, I've searched and haven't been able to find a solid answer.

Here's a teaser I took a couple days ago.

1-its your choice but for myself , no. dont pull out the harnesse, cut your hole in firewall before u put the engine in, or you can extend the wire, the only thing is the ea1 plug , do search, and make your choice from there, some ppl do that diffentetly and its also works

2- yes
Shoot... I alrighty have the harness out for the most part...

but thank you for the answer!

its alot easier to cut a hole in the bottom of the fire wall rather then extending every single wire in the harness.

this thread will show you what you have to do to your harness to get it swapped properly your self.
