hi guys. my rear lights don't work.ckecked the bulbs which are ok, and the brake lights work ok. looked at the wiring by the rear light and there is a black wire thats not connected to anything. it just has a bare end ( as though there should be a connector on it) i was thinking that it was an earth but before i connect it to the frame thought i'd better check in case i blow the fuses or damage something?
any ideas??
