s13 body harness wiring help!!

[kawitwofiddy]

hey guys i am having some trouble already with the wiring for the inside of my car. Its quite possible that its because i have a PDF file for a service manual and I havent got the best knowledge yet when it come to electrical. I could probably figure some of the wires out but it seems like part of the schematic was left out so i cant see wire colors or anything. i followed the wires coming from the audio fuse spot, and it seemed like it went to the door timer, and some other connectors. I'm confused and cant find anything in crazy depth on the internet. If anyone could help out that would be awesome i could use an smj pin out, wire colors, etc. I basically have to follow each individual wire because some were cut from previous owners, and i want to add some of the stuff he removed (radio, heater, other good stuff). im starting to think i should just hunt for a new body harness thats uncut. Again, any electrical knowledge someone could give me would be great.
