Wanting to install a set of fog lamps HD part # 68913-98 on my 04 RoadKing police, (The lights mount to the front crash bar) using the existing siren switch on the left handle bar. I have identified all the wires in the siren amp wire bundle and there is still power to the switch and the plug in for the siren so all my wires are already ran for me. My question is do I NEED to use the power relay that comes in the fog lamp kit ? or is that strictly for wiring the lights so when the high beams come on the fog lamps go out. I am not splicing into the low beam hot wire, this instalation is totally seperate from any and all existing lights. Thanks for the input. Tim
