"There is a single black wire (with connector) coming out of the ECU that is not attached to anything. To test the fans you need to attach this wire to ground for two minutes while the car is running. With the wire still grounded, turn the car off and the fans will stay on. After 30 seconds, un-ground the wire and the fans switch to low speed. The fans stay on for ten minutes.

The ECU is down in the passenger side foot well. You need to pop off the door sill trim and then pop up and remove all the fasteners holding the foot well panel. Best to go slow with this as the plastic stuff will crack easily. Once the panel is removed you can see the ECU mounted to the chassis. The test lead on mine was just hanging there, toward the front, but I remember someone saying they had to remove the ECU from its mount to get it.

The lead is black and has a female spade connector on it. You should test the circuit first to be sure it works. I used a male spade connector end and an alligator clip test wire. Connect it to ground for a little more than 2 minutes while the car is running. Turn the car all the way off and the fans should be running. After 30 seconds disconnect the wire from ground and the fans should switch to low speed and stay on for 10 minutes (it's timed not temp controlled). "

Basically connect this wire to a switch so you can ground the wire whenever you want to. Turn on 2 minutes before shutting the car down and the fans will run for 10 minutes on high speed. Unground the wire 30 secs after being on and they will run on low speed. Runs for the ten minutes.

Hope that helps.

 

I've also been thinking about doing this mod and had a few questions.
1. Any drawbacks? Does it wear out the battery a lot sooner?
2. Does this mod eliminate the need for a cool-down period? Can I just shut the car off after hard driving, switch the fans on, and that's it?

Thanks for any info!

Never heard of it wearing out the battery sooner...possibly if you have a miniature one? STILL need to cool the engine down. The fan will cool your engine bay but not enough to cool the oil flowing through your turbos. Fan mod is to help cool the car down, it is not a replacement for a proper cool down period.

 

Evot is right. Cruising low RPM, I usually pop the hood a few blocks from home and have the fans on(using parking lights). Let the engine idle for turbo cool-down in the garage/driveway with fans on for 5 min. You need circulation of the oil pump to cool the turbos, or you''ll "coke"(sludge up) them up.

Its like gettin' a piece of tail from a blonde model. Gotta warm 'em up to you, take 'em over the top, then cuddle with them to make them feel wanted after the dirty deed.

 

You can also turn on the A/C for a bit before stopping to turn the fans on. However the turn off when you take the key out.

 

Toadman --> pop the hood on the cool down drive - GRAND IDEA! YEAH!

(I still haven't removed the rubber strip at the windshield base, too afraid of fogging at the wrong moment)
