Harness wire id

[blacknight80]

hi guys,

I'm in the process of converting my carbed turbo to sfi and the harness I bought had the bulkhead connector removed. There are a few wires that have been left cut in the loom and I want to know if they are critical. I plan on using the stock dash and utilize the original gauge sensors and wiring. What is fed through the bulk head connector and more importantly what do I need to keep?

I did some more digging and was able to answer some of my own questions but a few still remain.

All of the pink and black wires have been combined into one large pink wire. I think I will need to either separate them or splice inline curses in them because they are all different amps

Brown wire is alt charge light/exciter. I think I will leave my stock setup for this.
Small purple is for the tcc power from the brake switch
Black was a clipped ground that has eyelet at the very end of the harness. where does this ground connect to the harness?
Grey is the fuel pump relay power
White is tach feed
I think the big red wires twisted together are for the starter
