HID problem with Hi/Low

Ok, so Ive had my HIDs installed for about a week..

The high and low beams are switched! I select high beam and the lows are on and vice verse.

I have the bulbs with the electromagnet base that moves the bulb in for lows and out for highs.

I guess what I need is a wiring schematic for the 2008 headlights. i need to know what wires actually control the high and low beams so i can isolate the problem. (2007/'06 is probably the same). Anyone know or have any ideas?

All the hid kits i've delt with were off ebay.....and my high low kit was the same way. So I simply flipped the plug on the ballast.....not the side of the ballast that goes to the bulb...the other side....flip that around. The "other" side i'm talking about....is the plug that's either in between your ballast and relay/hilo harness, or between your ballast and the stock headlight plug.

Flip the plug? i know what plug youre talking about, but I dont understand what you want me to do. Switch the wires that go into the plug? put the plug in backwards?

The plug out of the balast includes a ground (to the battery) and another wire that goes into the hi/low relay, then there is a seperate wire out of the relay that plugs into the stock harness.

Ok...so that didn't work.


Has any thought been addressed to swapping the wires at the stock plug?? That should solve the problem, but I think if you do that, your high beam lamp would be on when your low beams are on.....maybe. Possibly not, if that idiot light is linked to the multifunction swtich.

What I mean by swapping wires at the stock plug.......take your high beam wire, and your low beam wire, at the stock plug...cut them, and splice them to the opposite on....

meaning......low beam wire into the high beam wire. high beam wire into low beam wire.


Did you check out that thread that Tommy put up. He had a similar problem.

I know that coming out of my ballast going to the stock harness I didn't have a plug. Just 2-prong connectors that you plug into the factory pigtail... There's 3 wires on them though. One is a ground (In the middle of the 2 outside wires) one is for high beam, and one is for low beam. All you have to do is take a test light to each harness and figure out what prong on the factory pigtail lights up the test light. Then do the same for the high beam to make sure. Then just plug them in accordingly... If you plug the low beam in the high beam spot, switch the wires...

My kit actually had a nice plug that plugged right into the factory harness. That was the problem. I took it apart and moved the wires around and it works now. I would list what color wires were what (ground, hi, low), but Im sure each kit is unique so i wont waste the time.

Thanks for the help everyone!
