There is a relay in place already. All you have to do is ad a signal wire from the A/C clutch relay to the aux fan relay. I don't remember which ones they are but you can tell but turning on the A/C and waiting for the click at the relay.
I have added an electric fan in place of the mechanical fan and added MB relays to control the speed of the fan. I need to add a controller that turns on the A/C fan when I am moving less the 5 mph.
I bet someone will post the wiring diagrams for you.
