Hello Pete, Are you still around? Long time no speak!!!! I see your ac had a three prong resistor on top of the suitcase. Shouldn't that be a 4 plug connector? I read somewhere that tree was for non ac cars. However, my donor car had ac and had the three prong resistor. Would it be that I have a smog pump from california? I wouldnt think so. I also need a wiring diagram for the ac. I have a 12 gauge wire coming from relay that has a 20 amp fuse. Does that go to alternator? I have some extra parts from the donor if needed. Thanks again Minnesota nice.
