Do I need a specific D1S relay kit (has special connectors different form 9006), or do I use a normal/standard 9006 relay kit and plug them into the halogen high-beams? Anyone have a D1S relay harness link they can share?
Thanks for your help!
if you use the oem ballasts and bulbs and use scotts thread to wire them up so they have a 9006 plug coming off of them you need a relay kit for the 9006, this would plug into the connector from the headlamp and the one from the car and hook directly to the battery. Im not sure how a d1s kit would work cause ive never bought one but in my opinion i would go the oem route its much cleaner looking and less headaches in the end.
as for the wiring that comes with the headlamp you can dump it, save the bulbs and hook them into the wiring harness that is already on your truck. the harness they include wont be able to hook into your plugs, the only important wires on it are the ones for the bubls and ballasts, and this would be only if you use scotts thread to wire them other wise you cant use any of the wiring on it.
hope that helps sorry it sounds more confusing then it is really
