This is the electronic Fan controller sell by RD and others.

3 wires:

red: to +12v
black: earth
blue: earthed when fan must start, use this to control a relay.

Bonjour.......
Your wiring sounds about right, it must have a live feed for the thermostatic switch plus a wire to the fan (or more usually a relay to switch the fan on) and of course the whole thing must be earthed. This may help your wiring, you just need to add your earth wire to my drawing...

It is a method on how to wire up a thermostatic fan switch with a relay and also have an override switch on the dash (for when you get paranoid) the wire to the relay would connect to pin 85 on the drawing.

thank you.
I have too add a switch to control fan.
