I am about to do this upgrade to my 07 F150 and my question is if I have the electric fan.clutch can I just disconnect.the harness where it plugs into the main harness. From what research I have done it has a plug that looks round or oblong then a plug at the fan. If I unplug at oblong plug does Ford make a harness that would plug into oblong and fans and done. I ask this as an amateur at wiring but analytic thinker as the clutch is programmed into the PCM for all the cooling parameters. Thanks for the help. Joe
