1) You have to switch the ABS over or the DCCD won't work. You can still use a spiider controller but, the factory DCCD depends on STI ABS. The 05 STI ABS looks different than the one you show in the pics, if you've already swapped it over and you started with an 04, ignore me. Pretty sure the STI ABS won't work without the DCCD controller too. They talk to each other.

2) I switched the door harnesses so, the power mirror controls worked.

3) If you want the DCCD to work, you need to route the harness for the G sensor to right behind the shifter.

4) I switched fuel tanks because it looked like the wiring of the white connector under the rear seat was different between my 03 and the 05 donor. If you're just swapping the rear suspensions and subframe then that's a good time to switch tanks. STI pump is bigger too.

I like what you're doing with the calipers. Gold sucks.

Pretty sure the STI ABS won't work without the DCCD controller too. They talk to each other. everything was swapped over to STI...when i say everything. i mean everything.at one point there was nothing on the inside or the engine bay. so DCCD will work. in the rear diff, did you wire in the temp sensor?

2) I switched the door harnesses so, the power mirror controls worked.
if the windows don't work then we will swap them, as we have them on hand. did you try your windows without switching out the door harness? or did you just swap it out, just incase?

3) If you want the DCCD to work, you need to route the harness for the G sensor to right behind the shifter. Yup, removed all the sensors from the sti and installed them in the wagon. both DCCD controls are installed as well.

4) I switched fuel tanks because it looked like the wiring of the white connector under the rear seat was different between my 03 and the 05 donor. If you're just swapping the rear suspensions and subframe then that's a good time to switch tanks. STI pump is bigger too.
yeah, swapped tanks as well. my question is did you swap rear chassis harnesses? They look identical...

1/4) When I replaced the tank it included the STI harness. That brought the harness for the temp sensor with it so, yes, I have the temp sensor hooked into the rear diff (works too). You didn't say what year your donor was, now I'm assuming it's an 04 because your ABS unit looks older than the 05 one.

2) On the older WRX's, the power mirror switches are on the center console. On the 05 STI, it's in the driver's door switch panel. I switched harnesses so, I could still have the power mirrors working. The power windows worked with either harness (sorry if I said windows, I mean "mirrors"). I switched the other door harnesses because the 03 and 05 harness were different for the rear doors. The rear doors on my 03 use 2 connectors and the 05 used a single connector. I didn't want to do any harness splicing so, switching the harness worked. It's not clear when subaru made the change your 04 donor might be the same as the older wrxes.


Which steering column are you using? STI or WRX? I found I had to swap the wiper motors. The wiper motors used the same connectors. Apparently subaru had changed the internal wiring because, using the STI steering column, the wipers worked when they were turned off and didn't work when I tried the other speeds. Changing the motor while leaving the actual mechanism for the wipers worked.

Lol, sorry my mistake i was being an idiot and reading what i wanted to see, not what was actually there. mirrors, windows, i was just thinking about the connector and thinking well if the mirrors dont work, then maybe the windows wont work.

Changing the motor while leaving the actual mechanism for the wipers worked. Thats good to know. i wasn't sure if that would have to be swapped or not. the column is the original one from the 2002 impreza 2.5ts wagon, so maybe we'll have to swap that when the sti steering wheel is going on. did you install cruise control on your car?

I'm using an STI column to match up with the wiring harness but, the STI bag was blown as was the clock spring. Basically, I'll have cruise control once I find a good used 05 steering wheel. For now, I've mated the WRX clock spring and wheel to the STI column. Since you stuff isn't blown, I'd just install the full STI column/steering wheel. The cruise is all done by the ECU and the drive by wire throttle body so, not additional hardware is needed.

I am having problems with my airbags currently. The problem is once the airbag controller deploys the bags, it has to be thrown away and it's a $700 part and the airbag wiring is different between the 03 and 05. Again, I'm waiting for the proper parts to show up used. I doctored the wiring to make it look like the airbags work and to get through inspection.

are you reffering to the sensors in the frame rails, or the little computer below the center console.

Computer below the stereo. Once it deploys the bags, you can just toss it on the junk pile.

yeah. bags weren't deployed in my donor, as it was a theft recovery. i have one from an 02 if it will work for your car, but i think you already said its different.

I switched both the inside harness and the tank harness. The tank harness was still attached to the STI tank. I switched the ENTIRE tank. When you switch the tank, you should automatically get the correct wiring.

Yeah, i have the tank harness, so you replaced all the wiring that has to do with rear radio speakers, taillights, etc?

The white connector harness is only for the tank parts. Fuel pump, the sensors, the emissions canister. It also contains the harness for the diff temp sensor. I did replace the upper harness to the back too. It's the one for the the rear lights and so forth. The speaker harnesses are on the doors.

Yeah, gotcha. we got the fuel pump wiring all sorted out. just spliced the 2002 2.5ts fuel tank harness connector onto the sti fuel tank harness, just had to go through and make sure everything went to the correct place.

How often does your rear diff light come on? is it really worth it to wire it in?

If you don't have it, the DCCD won't work. You could splice the temp sensor into the harness behind the dash though and just cable tie it out of the way. I imagine you could fake it with a properly chosen resister too.

The STI uses it to protect the rear diff from overheating. It only comes on if you're really driving hard like on a race track.
