Sounds like a plan, just need to find the wire I need to mess with... And what the heck these disconnected wires go to.
If you'll determine the wire colors, as best you can, that go to each connector I'll see if I can figure something out from the 1996 EVTM. But tell me what wires go to each connector, and give me an end-on shot of the connector as there are some drawings of connectors in the book.
As for cleaning the wires, I'm using brake cleaner on a towel. Doesn't seem to hurt the insulation and does a far better job of cleaning it than anything else I've used.
