I've been reading forums for a long time, debating if I wanted to do my own HID install. I finally pulled the plug after reading up on some DDM Tuning lights/kit and I can say it's all kinds of easy. Total time about 45 minutes. Plug and play, simple. I've never done an HID swap, nor am I electrically inclined. However, you CAN'T GET IT WRONG.
Ordered the 35W/5k setup and winged it (with help from people here (thanks!)). Two things made it last as long as 45 minutes is because I couldn't access the driver's side light without pulling the inner wheel-well plastic and I plugged in the male end to the female end, closest to the bulb, backwards (which made it not light up; once I switched it...voila!). That probably would've brought overall install time to about 30 minutes.
I'm extremely satisfied with the results. I love the bright (not too bright) white light over the (now, by comparison) dim and yellow OEM lights. They cast a shade brighter and a better distance. Also the light is distributed more evenly and greater throughout the cast. So, without further ado...
Step 1: (I worked on the driver's side first because I knew it would be more difficult because I can't fit my hands into the space)
Pull off inner wheel-well plastic to access driver's side light (I didn't take a picture because it's in the manual). I only pulled out 6 quick fasteners.
Step 2: Reach up into bay where lights are and grab the OEM bulb, turn it (left or right about 90 degrees) and pull it out.
Step 3: Disconnect the bulb from the wire harness by pressing at point where wires meet the male plug and pulling (opposite my thumb)
Step 4: Plugging in. This step is foolproof. There's only one way the connections can be made, however, you can get one upside-down (as explained earlier). I plugged everything in, then slipped it down into the void spaces (closest to where I mounted ballast), then plugged in the HID bulb. **Note: cut off plastic, rigid white ring next to orange silicone ring. If not, the connection will not be air/water tight...you know what happens next.**
Step 5: zip tie ballasts and wiring to inside of body panels. As long as the ballasts and hardware is below where the fixed rubber stoppers contact the hood, then you're good.
That's basically it. Just repeat on passenger's side (except there's no need to make access through wheel-well. I'm 6"3' and my hands were able to fit in the voids available next to the washer fluid).
If any of this is unclear, please let me know. Also, I'm only going to write that this works with my specific HID kit (35W5k). It probably applies to other DDM kits, but I can only guarantee this works with my type kit.
I hope this helps.
