interesting, I have the two relays I used a few years ago when I rewired the headlight to bypass the j-box in the pre-HID days. Didn't get a chance to look at the bike this evening. Harnesses via eBay (quick look) are $20 shipped, but probably more Chinese junk. I'd rather wire up a harness myself if possible.
After my HID crapped the bed after a few months I went back to the H4, plus ff2oo Hellas for high beam and cheap Wally fog lights for low beam. We did a test up at Vintage weekend at Barber with the HID and ff200 lights, the ff200
completely overwhelmed the 55w Bi Xenon China crap. That and the reliability issues, along with total darkness without some sort of aux lights on board, killed that whole idea for me. I ride quite a bit, virtually every workday in the dark on rural roads. I need reliability and performance. I have both, now.
YMMV.
