Ok, so I'm making progress, but I cant find a wiring diagram that matches my car.
The only wiring diagram I have is for a Boxer with Air Conditioning which I'm guessing is different?
This car has no A/C and is a 1999 UK.
I have managed to power everything up by giving the circuit a 12v + and an earth.
The attached image shows the main 12v power in which is a black & blue wire.
Now here's the problem:
If I just put 12v + to the black/blue wire I still get nothing.
If I ground the motor wire (brown wire - ground) to the chassis nothing works.
But if I do both of the above together the whole system works as it should.
So somehow I the circuit is missing 12v + in AND an earth.
If I had a circuit diagram for this I might be able to make some sense of it.
Anyone have any Ideas to what is causing a 12v + and ground connection to be missing?
