91' Alternator Plug

[OpelTSi]

Its got 2 wires, Yellow and Black/Yelllow.

Does anyone know where are these wires go to?
Also should the yellow one have power to it when disconnected from the alternator?

Thanks

The yellow one is for your oil pressure guage, not sure about the white one...

You should take a picture to show us exactly what wires you are referring to, there is one more wire that is for your power steering pump idle control but I don't think that's what you're talking about.

Sorry I meant to say black and yellow wire.

Okay now only question I have now is should the Oil Pressure Gauge wire already have voltage?
