i read the willie's tech article on fan control and think it's great. i need help with a few things, however.

1. where do i get the hayden 3647 unit? i've called napa, advance, 2 pep boys, summit, jegs, and searched the internet. can't find it.

2. i need to wire my manual switch straight to the battery for cooling in the lanes at the dragstrip.

3. the switches in my switchbox are all lighted, i need to make it work with that.

can anyone help?

 

I also am looking for that hayden switch.... anyone know where I can find some kind of thermal switch that closes at around 180 deg?

 

Just a tip, but you dont have to do all that work. Simply turn the ac to on and put the key in the run position and the fan will stay on. Thats what I do at the track, works like a charm.
