72 Chevelle Dash Swap
I am replacing my sweep dash with no a/c out with an ss style dash from a 72 monte with a/c. where do i get my blower switch power from? is there already wires in the harness or do i need to add some from the old harness?

The existing power feed can be reused on the new blower switch.
The wire should be #14 brown.

Doc here, :pimp:

I'm Not sure the blower switch needs to be changed..It will operate the same (speedwise and on/off) with or without AC...

Where the changes might come in , is the vent door (if electrical) on the control head for opening and closing the vent doors, and activating the AC Clutch. These CAN be mechanical, (cables) , or Electrical (micro switches) , or Vacuum operated.

IIRC, all the wire for AC should be in the Harness already..but not sure about that..I think they ran them as spares in a Non AC unit so they wouldn't have to discriminate between Non and AC harness on the line..(one fits all) so compare between the two and see.

Doc :pimp:
