Alternator 4 Plug Wiring

[Thom]

Hey guys,

I've replaced my alternator but the plug was brittle and fell apart when I tried to unplug it!

I've got a replacement plug but don't know the order of the 4 wires.

Does anyone have a pic or know the wiring order?

Thanks!
Tom

Pin 1 = Black/Red
Pin 2 = Red/Green
Pin 3 = White
Pin 4 = Yellow/Black

I've rewired the plug and on idle its sitting pretty around 14.4v, but as soon as the car gets up to temperature and I apply any revs it will start overvolting (17v). (though if I tap accelerator before its warmed, voltage stays consistent)

I've triple checked the crimps and they seem ok. Am I right in thinking this is an issue with wires for pins 1 or 4?

Pin 1 = output from alternator to ecu?
Pin 4 = signal from ecu ?

Any ideas before I order some new pins and redo it?

Cheers
Tom
