There is a ground point located below the filter housing. Remove the 8mm nut and place the Black ground wire here.
Reinstall the air intake and filter assembly. Run the power lead and relay to the fuse box located on the passengers side of the engine compartment. There are two common ways to do this. You can remove the covers in front of the radiator and tie wrap the wire to the braces or you can run it along the wiring harness in back of the radiator top. For ease of explanation I ran it the latter.
The clips can be removed by using a flat blade screwdriver. The power lead can be placed in the clips along with the OEM harness. Do not connect the power, yet. Next, remove the passengers side light like you did on the drivers side. There is a ground point located below the light just like the drivers side. Connnect the ground. The ballast, starter and relays can be attached to the car using 3M tape. Here are a few examples:
The resistor is mounted to the fender well and connected to the white and black wires of the resistor.
Another place to mount the relay and excess wire is under the fuse box. The box can be tipped out of the way by manipulating the tab on the side. It is the one that is off center.
Remove the power nut under the red cap and attach the power leads at this time. If the cable is removed, the power leads can be located underneath as seen in the picture above. Once the wires are in place and everything is secured to the engine compartment it is time to try out the lights. Here is a picture showing the HID's on the left and the OEM's on the right.
If the lights flicker, revisit the resistor installation and make sure the wire insulation has been penetrated by the wire tap. The pictures don't do justice to the amount of light the HID's throw out.
