Does anybody know what the function of each wire off a '98 Legacy GT (EJ25) alternator is ?

There's a connector with 2 wires, b/w and white. The b/w one if for the alternator light. (That's the only thing I know).

 

There is a terminal with a little nut which also has a white wire, I assume this one goes to the Battery.

 

So what's the other white wire from the connector for ? Is this a separate powersupply for the wiring harness ? Do both wires put out the same power ?

 

Thanks,

 

(BTW, I'm putting this motor in a '70 Beetle, so I can't just trace the wires

The other white wire just goes to the battery, the same as the big fat one that's connected tot he screw terminal. It's for the field windings of the alternator.
