I don't want to cofuse the issue by guessing, and my wiring harnes is balled up in a storage unit so I can't look at it - sorry I can just give you the info....
Not sure where you are at on your car and maybe it seems expensive but wiring diagrams from theis site are well worth the money IMO.

Not to mention the service manual available on this site.

When you match the color wires to the colors noted in the manual you can figure out which harness is for what. Takes a lot of time though. Definitely recommend getting a copy of the service manual.
