Anybody know exactly what I would need and how I would go about adding a fan switch for these hot upcoming track days in Alabama?

 

If you're looking at just kicking the fans on at stop between laps just hit the A/C. My temps last season (Washington Summer ~100F on a couple occasions) dropped from 210 to 189 in a couple minutes. The extra load is negligible and your engine temps will drop like a rock without having to run an extra 12v switched power to the back of the underhood fuse panel.

 

I would do that but I'd be afraid of dropping water on the track, and the guy who runs the track checks street cars for water from the A/C. :/ and if he finds it, you can't run anymore lol

 

Wow....that sounds like a silly track rule. I could understand if there's a 12" standing puddle of water under the car or a stream coming off it, but the couple of drops that are going to hit the ground and shortly after evaporate won't cause an on track issue so long as you're not pissing all over the start line.

The right way to do this though is to run 12v from a switched source (anything that comes on normally with the ignition) through a toggle switch, then into the back of the fuse panel to the fan relays. You will want to add a diode per fan relay to the normal switched lines so that you aren't forcing 12v back at the ECU.

 

Or have your tuner turn the fans on at 190 or 185 for full

 

Alright I will try this and see how it goes lol

 

I haven't tested this, but you might be able to pull the A/C Clutch relay fuse and have it turn on the fans without running the A/C.
