I heard only the oem parts will work with it... guess I could try a generic one just to make sure, and if it works then I could get a good quality one from here...

Remove brown wire from the switch box and connect it to either of the yellow wires on the rectifier.

FYI,
I just bought an original on Ebay. It actually had the cable and plug that goes directly into the control box. I believe there were a few more. Might not hurt to take a look
