I bought a HID kit and am having problems installing the set up. You would think it would be easy. Just find out which of the 3 wires is ground, low beam and high beam. Well we tested the 3 wires and found that the headlights are wired in a positive ground setup. This mean the ground has power until you turn the headlights on, then the power is switched to low beam and the ground actually turns into a ground. Does anyone have any info on how to isolate this without rewiring the headlights? My truck is a 00 Dakota 4.7.
