    Anyone know the function of this terminal? I know there's probably a simple answer for this one, but I can't seem to come up with it. The little round terminal at the upper rear corner on the back of the instrument panel, driver's side. The first picture shows the terminal and the green wire beside it slips on it. The second picture (taken before disassembly) shows the wire from the panel going down to a relay and the other green wire coming out of the relay connecting to an 'accessory' fuse on the fuse panel. That's a three wire relay, but there was no additional wire coming from the third port. Searched the wiring schematic, but nothing there (as usual since it goes to an accessory fuse). I removed the small back plate where the water temp and oil presssure lines feed in, and there's a small gauge wire going straight down from that terminal to something, but can't see it. At last resort, I can remove the back panel to the instrument package, but it's all restored and wired up and looking for the easy way. Anyone got the answer, and what about that 'third' empty port on the relay....?

    Confused on this one.

    Yes, it certainly is! Just got that info passed on to me by email from the instrument restoration guys earlier today. Wasn't aware it had that feature available. I appreciate your post and thanks for the 'heads up'!
