Making a little (more) progress. Traced (and fixed) the Back-Up Light issue. Had a problem with the contacts on the switch. The contacts (seem to) have rotated around. The insulation over one of the female spade was completely melted, and the two pins on the switch were shorting.
I cleaned all that up, separated the terminals, put an insulator between the switch terminals, and a wire sheath over the harness to the switch.
I am surprised they now work with the the lights On / Off, with the ignition in Run.
I figured the short would have blown the fuse, or my BU lights would have been on all the time, but, I can't complain about the fix.
Anyway - another task behind me.
Now - on to fixing that Yellow Wire!
Thanks -
