I own an 05SuperCab Lariat. I ordered HID's offline for around $150 I ordered Bi-Xenon bulbs with a relay harness with them. I went to install the relay and the plug-in into the stock harness didnt have the plastic piece used to plug into the stock system. I installed it anyways and email the person online about the problem. He sent me a new harness and I removed the first and installed the new one. Even with the new harness I am still experiencing the same problem. The problem is...I turn my lights on without my foglights on and the lights will NOT turn on. If I pull out on the switch to turn my foglights on my lights will come on. When I flip on the high beams there seems to be no change in brightness(already on highs)! I can turn my foglights OFF and turn my high beams ON my lights will come ON. Im not sure why it does this basically I dont have any lights at all on low beam settings, also I can turn only my parking lights on with the fogs on and my HID's come on...Any suggestions? Also when i turn my lights to the off position or turn my foglights off I can hear the relay flip over to what seems to be the low beams then turns off. Any info would be greatly appreciated!! Thanks Guys
