How many sensors do you have there? Three or four?

The green sensor is normally in the very rear of the head. That "should" be the sensor for engine control.

I don't want to second guess here - U.S. Specced cars are different from Euro's and cars specced for the R.O.W.

In the later models with dual fans there are two relays
one actuates the fans at low speed - AC derived operation
one actuates the fans to high speed - sensor derived operation.
