I didn't intend to get the OBD connector in the pic. Sorry about that.
I don't have a radio installed - at all. So those connectors will be getting taped off. Thanks though.
As for the HVAC, there is nothing electronic on my HVAC controls. I have two "stickmen" as Rock Auto calls them. The only thing that takes power are the mini bulbs that light up the HVAC controls. They are super tiny.
Well, then, we are left with the mystery of the third connector. Oh and another mystery connector dropped out from near the ashtray when I was removing the dash yet again. I think, however, that that one is for the courtesy light in the foot well.
So as it is now, I need to get another door jamb switch and root through my spare bulbs drawer and see if I can match something up.
