lol. it will also tell you in the handbook. you shouldnt need to do this though. run the lights from a live feed from the battery with an inline 20 amp fuse, to a relay, another wire from the relay to the swittched live for the headlights (scotchlock connector) and another to the lights. remember and earth the lights themselves though. that caught me out for half an hour. DOH. couldnt understand how they wernt working. if you buy a relay kit it should explain all that in the instructuctions i would have thought.
