well I followed your directions, found a ground wire that wasn't attached to the frame cleaned up the connections and attached to frame, everything works, climate control, air conditioning, and radiator air conditioning fan works. Couldn't be happier, you guys are great

Thanks for all the effort and time it took for everyone to answer.

Thanks again John

purple wire has power going to it 5.8 volts
black wire has no ground
and the compressor has no ground or power going to it

ps. if I get a remanufatured ecm do you have to have it programed for your car
Again thanks for all your help John
