For anyone wondering, my rig gave me no more problems after Ken tweaked a couple of the contacts in that bulkhead (or is is it "banghead"?) connector - ran fine all the way home, even with a stop for dinner by Cabela's along the way.
Tonight's commute features a stop at Radio Shack/Autozone (within a block of each other) to pick up contact cleaner and an appropriate anti-oxidation treatment so I can clean all that nasty old anti-ox out and retreat. Will give the rest of the contacts a little bend while I'm in there too, just to make sure all is touching properly.
You know, I'm really hoping that this makes for "three" (Brake lines at RocktoberFest, gas tank in January, bulkhead connector) so I can have a smooth outing next time...
I have pics too, was too tired last night to bother with posting them. Coming soon, though!
