I just spent an hour trying to install them. I don't think they are plug and play.. the wires that provide the power to the ballast has two prongs, but i do not know where those prongs fit because it does not fit into my factory harness that powers my head lights....do you have any specific directions for installing them on 2005 Pontiac G6. secondly the factory wires for my highbeams and lowbeams and turn signals are fitted into the one factory grommet. so once i install the HID bulb, i have to retrofit the wires so that it just pokes out the side of the factory grommet because it is impossible to cut it without losing my highbeams.... any suggestions??
