I am fixing to install my ls1 fans in a couple of weeks. i bought the permacool wiring kit with adjustable thermo. I will need 2 relays for the fans. Will I need another relay to turn the fans on with the air conditioning or what and where do I hook it up to make them come on with the air. I am also going to hook up an overide switch to turn them on and off manually if I want.

i am not familiar with the premacool unit, but, you should only need a total of two relays anyway. at any rate, definately isolate your A/C unit with a relay.
