Headlight wiring question

Recommended Posts

I'm installing a "plug n play" HID bulb in my high beam. The HID harness has blue and black wires that are suppose to be pluged into the bike's headlight connector. The bike's connector has one side that is white with a single wire coming in and the other side is a double brown wire. Which is the positive side? I looked on my official BMW manual but there is no wiring diagram. I'd appreciate any help you have on the correct hook-up. tks

Figured it out. I just built a test harness and checked it out. The double brown is negative and the single white is positive.

Just a FWIW - Brown is ALWAYS ground on BMWs (cars and bikes..)
