I just ordered a new Dorman fan clutch for my 2003. When I replace I would like to utilize a switch on the dash to engage the clutch when I want to, lice the a/c does. Has anyone done this or do you know which wire on the harness engages the clutch to lock it up? I just thought it would be nice to be able to do this without having to turn on the a/c. Any input is appreciated.
Man, I don't know if you can do that safely. You may fry something. But heres what I show. My program won't let me copy wire diagrams, but I'll just tell you how they are listed. All but one wire go straight to the computer. If you backprobe power to the wrong wire, you are gonna fry either the clutch or the computer...
Dark Blue is 12 volt supply from fuse 36
White is "Sens Sply". I'm assuming a 5 volt reference wire.
Orange is "Fan Spd Sens". I assume the speed sensor
Black/Light Blue is a ground shared with several other sensors.
Light Green is "Sol Ctrl"
If I had to *guess*, I would say ground the light green wire. First, check the white wire with a dvom to confirm that has 5 volts on it.
You may cook something, set a code, put the truck in limp home mode, theres no telling... Use this info at your own risk. But thats your wires
on my 05 i was wondering if the wire is brown and orange bc the guy that hooked mine up tapped in to that wire right at the computer but it is causein my truck to die when i flip the switch off sometimes and it is throwing these codes, p0480
