I got my wiring harness from nelson. It has a wire that goen into the pcm.

I'm in the process of doing mine and its alot more expensive than I thougt it would be. I ended up needing a bigger alternator, replacing the big 3 wires, getting a tune, thermostat, and then I will have to go get my crank relearn flashed.

And I thought this was gonna be a $200 mod. hahaha

dont use a vsc because they suck and break on everyone buy a good wiring harness like the one from nelson performance.great quality and install is a breeze. the harness and fans are all you really need. alternator is optional(but strongly suggested). youll have to fab up some small brackets to mount them up. if you go with allens harness youll need to have pin42 turned on in your pcm.

When the temp gets to setting, it energizes a solenoid and turns both fans on, and when it drops, they turn off. It comes with most of teh wiring, but I had to extend the wire to the a/c compressor. PM me and I'll let you check them out one day when youre in town
