Finally got around to doing this today, I'm going to try and make this post as detailed as possible to maybe help someone out in the future.
Clear headlights and corner markers from Ebay seller parasitesingle
Clear turn signals bought off of another forum
DDM Tuning 55w 5000K Raptor HID kit
Zip ties as needed
One ring terminal
Here's how it looked when I started:
Its funny how the orange lenses and diffuser headlights don't seem so bad until you've seen the rig with the good stuff installed!
Pull the grille and headlight surrounds. The headlight surrounds can be a real PITA because you've got to snake your arm around between the radiator support and batteries to get the 2 11mm nuts off of the turn signal lenses before the surrounds come out... not fun. Next pull the header panel out. This step isn't completely necessary, but makes getting the headlight housings out way easier. There are 11 8mm bolts holding the header panel in. You end up with this:
Remove the headlight housings from the header panel. I use a pick to help remove those dang clips... once you see one and fight with it for a while you'll figure out a good method that works for you.
Now you get to figure out how to run the wiring for the HID harness. The kit I bought is a high/low kit and has this little electrical gizmo box:
I mounted it on the passenger side of the header panel with a self tapping screw:
The HID harness comes with a connector to tie into one of the factory headlight sockets. The kit didn't come with instructions but a quick phone call to DDM got me the info I needed to get the wires in the right spots. Blue (high beam) to the left, brown (ground) in the center, and white (low beam) to the right:
The wiring going to the driver's side headlight I ran along the factory wiring harness and zip-tied it in place.
Now, time to figure out where to put the dang ballasts:
There are two ballasts (one per side obviously) and the DDM kit doesn't come with any kind of a mount for them, so I bought some 24 gauge sheet metal at Home Depot and used my superior sheet metal fab skills to make myself a couple mounts:
So... where to put the dang things? I was having a hard time finding a good place for them that the wiring harness could reach. As luck would have it though, the OBS header panel has a spot in it that makes a perfect place to mount the ballasts. DDM said not to put them behind the grill, so I mounted them on the back side of the header panel using a couple rivets to hold them in place:
Ballast mounted, this is the rear side of the header panel
