Attention: TDR Forum Junkies 
Anyone tell me how to wire in a seperate switch to control the fan clutch... wired in a seperate switch to control my A/C compressor, seemed to be OK when the head pressure came up this afternoon. But tonight after I was sitting in the truck talking on the phone, I guess it didn't kick in like it should and the blow off valve on the A/C pump blew off some pressure. Would like to wire in a switch to control the fan clutch for like when I'm loading/ unloading and not have to worry about losing all my refrigerant. I know some one out there knows how to do this, i can't be the first to attempt such things!!
