Hooking up a trans cooler fan.
Hi all, my trans is running hot so I just added a larger trans cooler with a fan. Any thoughts on where I can hook up the power for the fan? I'd like it to run full time with the key on.

Re: Hooking up a trans cooler fan.
Most of the pink wires in the engine bay by the passenger side firewall are key-on 12v. You can use that as your signal for a relay and a fused 12v circuit to run the fan.
You probably don't need the fan though.. I would be curious to see what your temps average without one an a larger cooler.
