2004 VW Jetta TDI BEW
Ok after many days of troubleshooting, testing pins, the alternator, the battery fuse panel, and the fan control module, we think our next step is to replace the alternator harness. My husband is thinking of building this harness himself but doesn't know how exactly it is put together inside. Since this is our only vehicle we want to get as much info first as possible before taking the old harness out and rendering our vehicle out of commission. What he and I are wanting to know is do those small wires with the plugs connect into the main big wire that runs from the alternator or are they separate inside? that big bundle? The pic is of the harness we would need should we have to buy the actual thing and not make it ourselves.
