Unplugging the bulb can be kind of hard if the plug has never been removed. It took me a while to wiggle it out but wiggle the connection side to side while also pulling back slightly. Eventually it'll come off. Remove that clamp of wires on the driver's side to make it easier on yourself. Passenger side has more room to work with

Now depending which kit you got the HID bulb will probably be connected to two plugs which go into the ignitor. Best way to get the bulb in with the wires is the feed the plugs through first. Once that happens the bulb will slide in easily.

Also, make sure the notch on the bulb housing is facing 6 o'clock. I say this because the bulb clamp will hold the bulb in place but it won't be fully in. This can cause your light dispersion to be weak. Make sure it's all the way in. You'll be able to tell because the light dispersion will be full. It'll take some careful posteuring of your hands but a bulb adjustment at night time is a must if you want full light dispersion out of the projectors. I've done 2 sets and I manage to get 1 done correctly and usually have to fiddle with the other

Post up if you have any problems
