12v Switched near Radiator

Only the lights have switched power at the front of the car (maybe an AC lead) but the lights have power available all the time, but it not switched except for the headlight switch.

You might consider running a new fused accy positive wire and a thermostatic controlled fan switch.
My fan comes on at 210 degrees and shuts off at 190 no matter if the key is on or not or the car is running or not.
It has complete control regulated by the cooling system temperature and what temp I set the switch at.
Been working flawlessly for four years straight of daily driving.
