Alternator wiring.

Im having trouble identifying the wires. The connector has 3 wires. So total a 4 wires system

Which one is which?

I know the solo red wire is the BATT

And the connector has a red, yellow, and brown.

Re: Alternator wiring.

Trivial questions for this sec gen guy...I would think common knowledge for the 3rd gen crowd.

I just went to a single wire setup for ease.

Re: Alternator wiring.

Never seen a yellow wire in the alt connector and Ive disassembled about 40 3rd gen harnesses

What type of alt are you using and we'll go from there
