I just bought a new Bosch voltage regulator. The old one is not a OEM and has the wiring harness molded into the case. So I need to cut the wires and use spade crimp connectors on the new Bosch. So the problem is I have a Red, Black and Green wires on the harness. The terminals on the regulator are labeled: DF, D-and D+. Is it a straight through connection? Whould I be better off buying a new harness with a double ended plug connector?

Thanks, Eddy

This help?

Hmmm....

Well assuming the brown wire in the diagram is my black? wire, then this is a great help.

Thanks Ed.........

Eddy the voltage regulator should plug directly into the relay board. That is the only way to do it not worth all of the trouble to try to splice wires!

I agree with the Doc. I think you may have an incorrect replacement. Show us a pic. The bus regulator will sorta work. That may be what you have now.

I bought the part from Bow Wow, a VW part store. They told me it's the correct one. I do know the regulator in the car is not a factory original OEM. This one is part # 0 192 062 007. I think I will return it because I am not crazy about adding the stake on terminals when there should be a molded plug, which is fool proof. I will try to order the correct one on Monday.

Well made a few calls today and found out the harness is about $175, used. Way too much for 2 plugs and only 3 wires that is about 3 inches long. Does anyone know if I have the correct regulator? See part number above.

Thanks
