Note there is no noise at al if I remove the ulf module - the noise is only there is the ulf module is connected. I don't think the gain thing is a problem but more of an observation.

Tonight I decided to unplug the rca patch cable from the 26 pin connector to the Alpine amp per the suggestion on the Crutchfield link. No alternator whine. So, it seems that is where the it is picking it up but I don't know where along the line it is grabbing it. The patch cable is cat5 cable with rca jacks soldered on one end and the other is soldered to the bmw leads that go into the 26-pin connector. These have the pins pre-crimped and soldered so I know that end of the pins going into the connector are good.

I'm guessing I should redo this? What do you think?
