Everything installed just one question. The A/C blower switch on the 73-87 GM non-air controller that is suppose to be used by the kit only has 4 wires. The wiring diagram from Vintage air has 5 wires.
A/C controller has- Brown, Brown/orange, Green, Black
Wiring Diagram shows- Blue, Yellow, Red, Orange, Black
I am sure it is simple. Does anyone know what to hook up?
