Got the aux fan running via the temp switch. Thanks all.

One question still remains unanswered:

What direction does the aux fan need to turn?

Any answers to that question would be very helpful and appreciated

It needs to turn in the direction that blows air from the front of the car towards the back of the car.

I'm having a hard time figuring out how it could be installed to blow any other way???

Wouldn't the fan motor run backwards if the wiring polarity was reversed? Admittedly, someone would have to go out of their way to do that.

Not all DC motors will run backwards. This one however might be "low tech" enough to do so.
