Just wondering if anyone can help me out, got a 2003 ford ka van and someone has cut the 3 pin plug off and botched all the wiring.

When i got it the battery light is always on and when we looked the wires are all hanging off.

We got a connector of a transit which fits but the colours are all different...

can anyone tell me what colour the following cables are?

Pin 1 = Alternator Feedback

Pin 2 = Alternator Load Request

Pin 3 = Reference Voltage

I know which pin is which as plug is marked! just the colours im stuck with!
