What would be the easiest way to tackle this? I want stock radiator fan functionality retained for both my AC (pusher) and radiator (puller). I'm going to install a 180* thermostat so I just want to wire in a switch to flip the fans on when in stop/go traffic or waiting in the staging lanes at the track. My coolant temps are perfectly normal for a stock car, but I'd like to get them down a bit during those driving conditions. I'm sure all I have to do is run a wire to the fan relays, but I'm not sure if I should go to the relays or to some random wire under the hood that's maybe easier to access. Anybody else done this?
