Double temp switch E36 325 radiator

[EOS]

I've just changed the rad in my M50 converted E30 to a E36 325 rad, now it has the double temp switch in the side of it which i'd like to use for my electric fan. The switch has three pins on it, and i'd like to know which one's which and does what? Does any one know or have a wiring diagram for it all?


Item number 10

1/ green/black = 12v+
2/ black = low speed relay
3/ black/red = high speed relay

I realise that this still doesn't show you where the pins are, but most things like this on BMWs are marked if you look carefully enough.

Like Brian said, there are markings on the temp switch itself to identify which pin is which
