Thanks guys,
I appreciate the input. Any thoughts on what the mystery box is, why he wired it in, and how to return to semi-stock running?
If this is some type of voltage regulator, could I just find a way to properly attach the new wiring harness leads to a "real" voltage regulator and still use my alternator?
I REALLY don't want to cut up my "new" harness and start down the same "hack" road as the PO.
