Locate the original fog light bulbs, which should still be connected to the wiring harness (if you unclipped the bulbs from the housings):
Remove the bulbs from the stock connectors. The stock connectors need to be cut off and replaced with the 9006 connectors, as that's what plugs into the HID relay harness:
I trimmed some of the excess wire from the 9006 pig-tails:
Solder in the 9006 pig-tail. Make sure you get the polarity correct. In my case, the yellow wire on the 9006 pig-tail connected to the white wire from the OEM harness. The black wire one the 9006 pig-tail connected to the black wire on the OEM harness:
Clean it up with some conduit and a zip tie:
Now, you have a true plug-and-play system, as the OEM wiring harness plugs directly into the HID relay harness:
The HID relay harness needs a good ground. This ground on the frame rail is in the perfect location:
Remove the 10mm nut, install the HID relay harness ground, and reinstall the nut:
For now, you're done with the wiring for the passenger's side. Run the second half of the HID relay harness across the front of the vehicle and over to the driver's side. Make sure to wrap the harness in the remaining conduit:
Use the same procedure as above to replace the OEM fog light plug with the 9006 pig-tail:
Mount the ballasts to the vehicle. I used the provided double-sided tape pad to affix the ballasts to the backside of the front bumper reinforcement, one on the passenger's side, one on the driver's side:
Plug the HID relay harnesses into the ballasts. You should be left with the relay, igniter, and HID bulb plugs hanging down. Using a #6 sheet metal screw, mount the relays to the plastic support panel under the headlights:
The igniters and HID bulb plugs should be the only items left to address:
I used some 3M double-sided tape I had laying around and affixed the igniters to the front bumper reinforcement, just next to the ballasts. This gets them out of the way and secures them. (No picture)
Connect the HID relay wiring harnesses to the power post. Using a 13mm socket, remove the post. Slide the HID relay wires onto the stud of the post, and reinstall the post.
***NOTE*** I had to notch the eyelets on the wires to get them to fit over the post stud:
Replace the cap on the power post, and shut the hood.
With the front bumper cover still removed, take the HID bulbs and install them into the OEM fog light housings. Just push them in slightly and they'll snap into place. Be gentle when doing this, as I found the tabs on the bulbs to be extremely brittle.
Once the bulbs are installed, slide the bumper cover back onto the vehicle. Slide the top of the bumper cover in first, letting the upper bumper tabs slide into the retainer under the grille.
With the bumper cover partially installed, get under the vehicle and plug in the 2 wires from the ballast to the HID bulbs.
At this point, activate the fog lights to make sure the HIDs turn on.
If all seems well, reinstall the front bumper cover in the reverse order it was removed.
Then end result should be this:
Headlights and fog lights:

Enjoy the fantastic light output.
