Aternator OB-I and OB-II

During a 2,5l swap I switched the alternator because the old one didn't charge well. Now I discovered that the new alternator has a different control connector. It now wants three wires instead of those two in the cars wiring.

Anyone who knows what to do or have the wirediagram for booth?

I got the plug with cut of wires attached to it with the new alternator. Two of the wires had the same colour as my original so I tried to hotwire those with no success.

When I measured the resistant on pins on the alternator it looks like the old one had one relay and the new one has two..
Maybe I should connect both relays to my one control signal?

It might be the alternator itself, but I would like to check the wirering first.


I have tryed to search the forum, but I couldn't find anything about the wiring for alternators. If someone made this topic and got answers before me, just link me to the page.

ya thats the millenia 110amp alatenrator. I take it your ze is a curve neck then.

s long as you have the bracket that goes onto the cylinder head. its a tad different than the others. That 3rd wire is a ignition source. So anything thats got power when the ignition is on. When I did it I ttok the power from teh plug for the fpr solinoid which I wasn't using. Next time I am just gunna run it to the fusebox.
