I admit I'm not that great with wiring systems, but I do understand needing a good ground. I have connected the new LED light array to the wires behind the licence plate on the RSV. I connected the signal wires and the brake light wire to the wires that are feeding the stock signals and brake light, and the ground to the ground wire the stock lights are connected to. The brake portion of the array is perfect, its the signals that are half brightness. As I said, if I connect the signal wire the to brake wire feed I get full brightness, so I know its not a grounding problem.
