Thanks all- I see you kind of did them both together. The car runs now, I was looking to do one thing, then make sure it drives (some times I miss this goal) and then do the other one. The dash is out, so I am thinking AC, then wiring- as I kind of need to put the switches in to test the wiring, and should have the dash installed to test the wiring- gauges and all.
I will go and buy some good crimpers/strippers for the job. The goal after all is an improvement over where the car is now...
So sounds like I should install the AC, leave out the vents, do the wiring, add vents, then the dash.
Well, that sounds simple.
