As requested, this is the write up how to install your depo ecodes. I am not responsible for any damages that may occur during install. Procede at your own risk.

Tools Needed:
Utility Knife
Assorted Screw Drivers
Drill
Wire Cutters
Shrink Wrap
Lighter
Band Saw

Additional Supplies:
9006 Headlight Bulb Connectors
Lexan
Weather Stripping

Step 1
Remove from box and remove the plastic wrap around the headlights. I left the plastic on the lens to help prevent scratches. Next cut the zip tie that is securing the housing.

Step 2
Use a knife and cut the square for the oem ballast. Be careful, the plastic is actually a lot thinner than you think. Watch the blade so it doesn’t hit anything inside either.

Step 3 (Skip if you are not using auto levelers)
Next, I would remove the Packing screw for the auto levelers. The packing screws on the depos are different than the valeo white ones. The depos are black and have a flat head screw and a black plastic cap. Turn the screw clockwise a few turns. Then get your pliers and turn the cap clockwise. Then you will have to unhook the end. I just wiggled it out but a small screw driver could help.

Now remove the levelers from your stock housings.

Now reinstall them into your depos. If you find the auto leveler is too short to reattach adjust your height screw so the housing comes closer to the back of the headlight. This will give you ample room to slide it in.

The auto levelers are a p-i-t-a to install. If I were to do another set I would leave them out. I also think it would be beneficial to install the levelers now since all the wiring is out of the way.

Step 4

Take your 9006 plug and strip the ends of the wires.

Locate the wiring harness. Now cut off the low beam H7 connector.

Now connect your 9006 connector to the new harness. I MESSED UP AND MIXED UP THE WIRES IN THESE PICTURES. BLACK GOES TO RED AND YELLOW GOES TO BROWN!


Step 5
Place the wiring inside of the housing. Pull the 9006 plug through the hole you cut for the ballast.

Step 6
Connect your ballast and mount it to the housing. I placed mine as shown.

Now put some screws to mount the ballast.

Step 7
Measure the size of the ballast opening. Mark it on the piece of lexan.

Now cut the pieces to size. (I used a band saw)

Step 8
I used clear lexan so I just peeled off the paper. Marked the holes and drilled them. Then applied weather stripping on the edges and screwed it in.


Step 9

Cut off all of the garbage on the bulb.


Connect the bulbs and install them in the housings. This is how I arranged all the wires.

Step 10
Put on all the caps and install the remaining bulbs. I just cut off one of the prongs on the blinkers and pushed it into the housing. It took some wiggling.

Finished Product


I have a lot more adjusting to do before I will post pictures of the beam cutoff. But, as of right now I am not too pleased. There is a lot of hotspots and the cutoff is wavey. Also, the fitment is not exact. You need to snip off some plastic on the bottom peg to get them to fit. I still need to install the city lights.
