No I bought the kit/parts from http://www.danielsternlighting.com
Its basically everything you need except the wire, so you put it together yourself (which is what I wanted). There are other kits you can buy that are premade though.

Jake- the AC compressor is turned on by a positive voltage. The ground/return path is through the engine block.
However, you may want to wire it so that fan runs any time the AC is turned on at all, not just when the compressor is running. I'm not sure of the easiest/best place to tap into that circuit, but the most obvious would be at the switch in the dash.

These work pretty good if there is room (first 2 items depending on fuse size):

Connectors

Well finished product looks pretty good, the "universal" brackets had to be drilled for new holes, i mounted the fan to the stock mounting holes on the radiator...no pics of intalled fan yet...

I got my painless wiring fuse block today, just as i was installing the fan, but decided ill install it a bit later.

The issue of wiring the fan to the ignition was pretty simple, i got a wiring schematic from the Toyota dealer the day before and piggybacked the ignition wire from the fan to the black wire with the yellow stripe in the engine bay fuse box, which is exposed where the harness plugs to the box...this wire is ignition hot and is continuous with the ignition fuse inside the cab.

When i install the painless kit ill splice into the 14 gauge wire already hooked up and add my accessory wiring as i go.

Little side note, it's well below freezing here in southeast idaho so the fan doesnt actually turn on even while idling unless i turn the air conditioning on and pull the throttle cable upto 3000rpm.

The air conditioning signal wire is not hooked up yet, it will be piggybacked to the AC compressor plug wire as soon as i determine if it is a positive or negative signal that turns it on... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

Jake, re-read the second part of my last post. <img src="/forums/images/graemlins/smile.gif" alt="" />

I missed that, obviously...ill have to look into where the AC button goes into the cab from the engine bay somewhere, im not too worried since i never use my AC, when Summer comes around it's in Seattle, so windows down is good enough for me. <img src="/forums/images/graemlins/kewl.gif" alt="" />
