I think the two yellow cables are not the control cable.you may connect the HID to the high beam ,so you need exchange the palce of your former light and HID.
Hope you can solve your question.
I recently bought an HID kit. It has two bulbs. When I installed it on my 2002 Mustang GT and turned them on, only the bulb that is not HID went on. But when I switched my lights to High Beam, then the HIDs went on. I asked a friend and he said that the cables were inverted. My HIDs have one black cable, one red cable and two yellow cables. They told me to switch the yellow cables but when I did, nothing happened. CAn anyone tell me what to do and how to do it. Thank You. I want my HIDs to turn on with low beams.
