I have a 3 pin speed sensor on the V6 and can't find/work out which pin needs the 12v (or earth) adding. Currently have the 2 pin plug which i want to replace with the 3 pin plug.
The sensor is on the car and it was a struggle with the subframe off so don't really want to take it off to test on the bench if I can help it.
hopefully someone can remember :-)
BTW, I have removed the speed module that came off the 406 as I thought this was just for the cluster speedo.
Found this thread but doesn't detail the pins...
