Ok, thanks. That helps if I was using the motronic system, but i'm using an aftermarket system. So I need to know which is the ground, 5v and wiper.

Ok, I think I've just worked this out-
I new pin no3 was ground, so from the diagram above, the only wire going to nothing other than the ecu is no2(making it the only one that can be the signal), therefore only leaving one wire for the 5v- no1.
ie-
No1- 5v
No2- signal
No3- Ground
Correct me if i'm, wrong.
