roger ... is the high speed wire a straight shot from the dash control to the blower motor (after stopping at the resistor array)? I should just check the wiring diagram I guess
 I have a new AC harness coming from AAW, and a new engine harness (V8 w/AC) also coming from AAW. May modify the blower wiring before installing.

On a stock '69, the fan switch just fires a relay via a small gray wire for high speed. Then the relay sends the current directly to the motor with a 12 ga wire. The power source for the relay is a 12 ga wire connected to the alternator. I would think the '68 was the same way when stock.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
