On the fan, if it's anything like the Taurus fan on my S-10 which is 3 wire one is ground and the other two were fan speeds; low-hi. The wires may ave a stripe or something on them to tell what goes where. Could look at a wiring diagram to see too.
I did drive the Heep around the lot last week, it drove and it stopped. It's a start.
Still have a list of crap to wrap up but after wrenching on everyone else's toys all day I don't even want to look at mine.
