If you want to find the air conn switch for the fans it's in the thermostat elbow, it's quite big on the V8 but for me it closes with the engine already a bit hot, so i used a fixed temp switch from Merlin Motorsport and adjusted the switch on temp by locating it 1/3 down the rad. Otherwise Wizard sells an adjustable thermostat like the Kenlowe one, you can wire the whoole thing from the battery then using a relay.
