Need some electrical harness gurus inside

[Boxersix]

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.
