Electric Fan Constant Running Wiring Option

[Zeorymer]

This how I did mine(It's on a TT, but it can't be too different for the NA.): Thanks to Mitch(AMZ Performance) for sending me some install recommendations.
Doing it this way will make the electric fan run only when the ignition is turned on, but for 100% of your drive. I guess you could use a thermostat switch if you don't want it to be on the whole time.

Wire looms come in handy:

Feed the positive and negative wires to a Relay. I chose this mounting location for the relay because I felt it was the best path:

From the relay there should be three wires, ground , remote/ignition signal, and power with a inline fuse . Ground the ground wire directly to the body somewhere close to the relay to get the best possible grounding. Next feed the power wire to the positive terminal of the battery:

Now feed the remote/ignition signal wire from the relay into the wire loom taking it over to the fuse box on the driver's side of the engine bay. I loomed it to go under the radiator support:

Straight under the fuse block:

You can use the Radiator fan relay as an ignition source:

In this pic, there is a screw(behind my big finger) securing the fuse block down tight. Loosen the screw to make feeding the wire under it easy.

Zeo...I've been looking for this write up...Very cool indeed. So the radiator fan relay can be used for the remote start? Nice ;D

I guess you could use a 4-seasons thermostat housing cover (http://www.thepartsbin.com/brands/4-seasons/4-seasons_thermostat_housing_cover.html) switch if you don't want it to be on the whole time.

Great! I think it would be better to start off with a simple setup. Try looking for a nice thermostat housing cover.
