is there any way you can get a picture of the relay harness and the ballast/bulbs?
I am thinking you have to have the blue connectors connected on both passenger and driver sides because the 9007-2 kit uses that special wiring (the thing with the blue connector, the black box, and the 2 wires coming off the box) to switch between teh hid low beam and the halogen high beam. If only the blue connector was connected on the passenger side, then how is the driver side getting the signal to switch between beams?
this is why it would be nice to have a picture of the harness laid out because i don't know what both sides of it look like. My hids are bixenons so i dont have that extra blue connector wiring
