Next, I wanted to get some stuff done with my harness.
Because the stock headlight wiring is thin and runs from the fuse box to the steering column then to the headlights, the high powered HID ballasts risk melting it.
I used 10awg wire. The 9004 is switched positive hi/low. I put a diode between them so that high beams or low beams will fire up the ballast. I then connected a 6800uf cap across low beam and ground, so that if for some reason I switch to high beams, the lights won't flicker in the half second that neither has power.
Then they trigger a relay, which switches power directly from the battery to the two AMP connectors for the HID ballasts.
