I just received a trinary switch from Vintage Air. This switch has four wires coming out, 2 blue and 2 black with no other color coding. The instructions indicate there should be a black/green wire or black/wire. Any help on hooking this up would be appreciated. I believe the two blue wires are for the fan control and the two black are for the compressor clutch.
Thanks.

I am going on memory here. I dont have the car in front on me. In the instructions it shows the wire to the compressor to be blue.

I had mine hooked to the blue wires on the switch but the compressor would not come on.

I hooked the compressor to the black wires. Blue wires to the fan controller.

Just make all 4 wires with spade lugs so if you need to swap them you can.
