I have still done nothing. I will be sticking another new fan switch in today to get me by. Just unsure which way to go still. I feel the plug swap may be over my head. I should be haunting Ebay for a used adapter harness, problem solved. That is my speed.
I've had enough heat w/o the fan so far but that's about to change. Been a mild December. Been getting by with closing a cut tarp in the doors and over the windshield. You all should try it, instant defrosted windshield!
Guess I'll go to Ebay now. Will post final results
