Need some electrical harness gurus inside
 

I'm in the process of swapping that EG33 into my 2002 WRX rally car, and I need to thin out the SVX harness to the bare minimum required to run the engine.. It's been so long since I even looked at the harness from the SVX that I have forgotten what is what. I would like tostart by just cutting out any clips and related harness that 100% definitely have nothing to do with the PCM and related functions.

Below I have taken pictures of all the electrical clips. This is the main harness under the dashboard of a 1994 SVX.

If you gurus could assist me in labeling as many of these clips as possible it would help me out tremendously. The pictures are numbers as s1- s18,so just replay by saying soemthing like s4 = radio harness, heater blower, etc.

S16 is part of the OBD system used for checking ECU codes.

So are the plugs on S-17.
S-9 looks like the TCU plugs.

wow, you really need a FSM wiring diagram section. that would help you out immensely.

Re: Need some electrical harness gurus inside
 

S12 looks like what connects to the front wiper control module, but that could also be the large connector in S2.

You've repeated S1 in the second post.

Can you post a picture of the whole mess spread out (doesn't have to be completely "neat"). That might help folks identify portions.

There's a separate harness under the dash that connects to the instrument panel ("combination meter"), radio, speakers, clock, cigarette lighter, and a couple of other things. That doesn't appear to be in your pictures.

Yeah, I'm really shooting from the hip on this one. I do have some PDF files of SOME FSM wiring diagrams as well as the pinout identification for the PCM. Using those I have been able to start tracing some wires and cutting alot of crap out. It's just a slow and tedious process, it's a mess of a harness when all unwrapped.

Basically I just need to be able to get the harness down to bones that run the motor, and have clean tach and coolant temp outputs that I can splice into the WRX dash(all else will run off WRX PCM). Fuel pump and harness battery power will be operated off a relayed/fused toggle switch panel in the center dash, so even things like the FP relay and FP modulator can go as I don't need them.
