OK, I have cell phone pics of all of this now, but need to use another pc to get them on here.

What are your AC problems ? does the fan come on at all ? what about the compressor ?

On my frigiking, I hooked it up to a bat in the garage to double check all this,
1 Green color ground wire, comes from behind the blower motor, goes to ground, probably is a loop terminal under one of the 2 10mm nuts that holds the heater box in. 1 Red wire comes from small wire bundle taped as a harness from the front of the console, it should have an inline fuse holder there, runs around to passenger side of AC console on mine. 1 Blue wire also comes from same place as red wire, & it should run through the firewall with AC hoses up to the compressor, it supplies power to the compressor.

That's it, just 3 wires to hook up a frigiking.

AC compressor gets it's ground from the block or body, some may have short black wire running from bracket to block or body. And behind the console front plastic where the temp & fan speed controls are, you have a red & blue wire that go to the left side control, should be the temp control. There are 5 wire terminals on the fan speed switch, & there are 2 small coils of wire that have 3 wires hooked up to them, these are just low value, high power resistors, that are used to drop the voltage for medium & slow speeds.

If you want, it's easy to hook up a relay to kill power to the frigiking when the car is off, i.e. make it only come on when key is in run position. I did that to mine way back when & also added a heavier wire straight from the bat or fuse block ( I forget which, either is OK) to reduce the voltage drop that the factory wiring had, this made the fan blow a bit faster at all speeds, which equals more cool. I never hooked up a kill when heater fan is on option, never had a behr at that time, didn't know they did that, plus if you can run both fans, you can defrost the windows with dehumidifed air from your AC, a feature the behr's can't do :-)
