I've just installed a new B&M Cyo Premium head light on my bike to replace the Lumotec Classic that came with the bike. Everything is working well, except I can't figure out what to do with the ground wire for the tail light. The old head light just had one wire that ran from the head light to the tail light. The Cyo came with two wires: one that obviously connects the head and tail light and another with a white stipe on it (the ground). Any idea where the ground wire should go?
Two details that may or may not matter:
- My tail light is the B&M seculite (the kind that goes on the fender).
- The wiring for the tail light runs through the frame and is pretty new, so I didn't replace it. I just connected the new (short) wire that was sticking out of the Cyo to the existing wiring where it exits the frame near the fork crown.
Thanks for any advice you can offer.
