I'm in the process of hooking up my hids and I'm trying to figure out the plug for the bulb. I have a power and a ground wire coming from my hid bulb and its suppose to plug into the car's wiring connection (the christmas tree looking thing where the oem bulb plugs in) and there are three red wires on the back side that plug into the christmas tree; one has a green stripe, one has a black stripe, and one has a blue stripe. Can anyone tell me what these wires are? I'm guessing the black one is ground and green is power but I'm not positive.
