Here it is. There is not a thing on it that hints at how it should be wired..

[mattdeez]

it looks like a standard relay...unfortunately i don't know by memory how to do so. Look online for wiring a 2 way relay. not very difficult....also used in alarms.

The relay plugs into the small circuit board. The wire you see is the thermistor. I believe the little blue and yellow thing is the adjustment for the temperature.

Sorry for the lousy pics.

The other terminals should be ground, battery and possibly ignition, fan and air conditioner.

How to determine this is a little out of my expertise.

With out actually seeing it up close. I would guess the following:

The fan turns on when the coolent hits a set temp, the A/C turns on, or you manually turn it on.

With that in mind. If it is just a relay circuit, and I am pretty sure it is.

You want to wire it up so that either the switch, the coolent, or the A/C closes the relay and powers the fan.

once you figure out which terminal is which, it should be pretty easy.

Turned out it was a standard Bosch relay system. Thanks anyhow.
