Well I dove off into the electrical a little today, just to see what I was up against.. and it looks like it's going to be a project all in itself. I'm pretty sure that it has the original wiring still in it, since it's embedded in the fiberglass..
I've looked over a couple of the wiring diagrams to try to get everything straight in my mind.. but can't find anything that matches. I may be crazy, but it looks like the White wire is the ground...
White ?? (Only common color on all the fixtures, and it's split 3 ways behind the seat, so it makes me think it connects to everything.
Blue (Cabin Lights)
Red (Running Lights)
Black ?? (doesn't seem to go to anything...)
Anybody got any ideas or links I can research? Starting to look like it may be easier just to pull some new wires...
I've been called worse by nicer people.
