Can anyone who has H-D or other passing lamps on a newer Dyna let me know which fuse circuit they tapped into?
Boismier, the HD passing lamps come with a wiring harness. The main power lead is connected to the copper plated stud on the main circuit breaker. It has an inline fuse between it and a relay. From the relay a ground wire is attached to main vehicle ground. From the relay comes the wire to the low beam headlight wire with an on/off switch in between and a wire to the passing lamps.(from relay also). Hope this helps.
