I have a '95 Lt1 trans-am engine harness and theres a few plugs that go through a grommet in the firewall. They are rectangular. One is white, another is blue, and theres a small black one with only 3 wires. I've figured out maybe 1/3 of these (some are like brake switch, serial data link/mode wires, etc). I was wondering if anyone had already done what I'm doing and knew where each one went for these. Also I need to know the ones that go into the underhood electrical center (two good sized plugs and one really small one).

 

Maybe some are these?

 

Yeah, I think its C230 and C220. Do you know where each one goes in them? It's hard to tell from a diagram because I don't know where its going or coming from, I can only tell by the wire color/size which takes a long time. Also the 8 cavity plug and 10 cavity plug in the "underhood eletrical". I've only found a couple in those two, one of the pink wires goes to the coil, another is the serial data link, etc.
