I have a 67 Chevelle with air. I am using a non air dash harness. The difference is that on the non air harness the heater switch wires/plug to the blower motor switch are part of the main harness. In the air harness the ac/heater system has its own harness that plugs into the main harness with just one wire. Is there a wire on the non air harness that I can connect the ac/heater harness to and just leave the blower motor plug on the non air harness unconnected??
Thanks for any help
