quick question, wiring harness

what are you doing?
swapping the car?
If so then yes you need to take all the wiring out.
Depending on what your swapping in, you can leave in the trunk harness, roof chord and door harnesses.

well the fuel pump controller for the USDM Ej205 is on the trunk harness.
Not sure how people were wiring it in.

Pull all of the wiring out of the donor car except for the stuff in the doors. Don't throw any of it out until you are 100% finished and the car is running and driving. Only pull out the wiring from under the dash (and whatever else goes into the engine bay) from your RS.
^^^ OH YES! i learn that the hard way!

does this include the alt wire and fuse box?
I pulled it out and kept it just for the hell of it, but no you don't NEED it.
You should also have the wiring harness that goes with that 03 ECU.

The WRX harness is basically one big harness, not a seperate bulkhead, front, back etc. like the RS's. You're going to be doing a lot of cutting with the wrx harness to get to just what you need.

^Go through those pictures and read the captions, plus read the corrisponding story to it to get an overview on what needs to be done. Do NOT follow that article word for word because it is said to be inaccurate in some places. But again, its good for getting a little overview at what you should be doing.
I'm not trying to judge you anything, and I respect you for taking on a big project like this, but just from what I've heard it sounds like you need to do a little more research. Check out some of Brydon's threads, especially his sticky at the top of this forum. Also check out the "Good Wiring Help" sticky and read around
*edit* heres another good thread to follow along with:

I'm right in the middle of my swap. I'll be honest, I got all the wiring out, unwrapped and ready to start, when I realized I could do it... but it would take me probably until december to finish. Its a huge job! I ended up sending it out to GT (ECS is also a good shop for wiring)
