I did not take pics of the grille removal or the headlamp removal due to MOST people knowing how to do it. However, if you need a know-how on the grille removal please look here…

For headlamp removal, you have (2) 10mm bolts on the top side of each headlamp that holds them on.. Remove and pull headlamps off.
Location of bolts for headlamps…
The first thing we did was to hook up one ballast and check all of the HIDS to make sure that they were all working properly. When we hooked up the highs, as well as the lows, we noticed that the wiring on the HIDS were backwards from the stock plug. (ie: positive was not going to positive) so we had to switch the connector around on the new HID plug using the Dental pick or Tweezers.
NOTE: Orange wire is the Positive wire for the Stock Plugs!
Below, the red and black wires are those of the HID plug, the Red wire(positive) was going to the Blue wire(on the lows) and the Pink wire(on the highs) before we switched them to be correct (shown below)
After we checked all of the lights to make sure they worked, we started installing by placing the 9006 and 9005 HID Bulbs in the headlamps themselves.
One thing to note.. while trying to place the new HID bulbs in the headlamps, they would not turn and lock into place, we have to loosen the three screws on the back plate in order to get the turned into place. Them once they were securely “locked” we tightened the screws back down. (shown below)
After getting the bulbs installed for the Highs and Lows, we moved onto the Fogs. We removed the stock bulbs from the fog housing and put in the new HID bulbs.
NOTE: The HID for the fogs do not come with a plug to replace the stock bulb. The stock plug MUST be used for the new HIDS.
Since the Fog HIDS (H11) come only with the “prongs” the stock plug must be used.. all we did was unplug the original connection..
Then, plug the HID prongs into the existing stock plug for the fogs (Purple wire is Positive)
Then.. wrap each individual prong separately to give it an extra layer of protection…
Finally, we wrapped the whole plug a number of times for water resistancy…
.
Once we got both of the HIDS setup for the fogs, it was now time to choose mounting spots for the Ballasts.
NOTE: Ballast mounting is owner preference. I can tell you right now it is a pain to find a spot for ALL 3 ballasts on each side to fit next to each other. I chose to separate them and make sure they would be COMPLETELY secure.
My choice for mounting these ballasts were here…
One you have the Ballasts mounted, begin hooking up all of the wires. There are 3 main wires that need to be connected. 2 round plugs ( one set coming from the HID bulbs, One set coming from the Ballasts that meet together in the middle.)
And 1 “rectangular” plug(1 set coming from the headlamp/foglamp plugs and 1 set coming from the ballasts which meet together in the middle. (example below)
From Ballast to Plugs…(rectangle plugs)
From Ballast to HID bulbs…(round plugs)
Finally, Once everything is hooked up and mounted, reattach your grill…

and test them out. Some adjusting will need to be made for the height of the headlights. DON’T BLIND PEOPLE!.
Also, some adjusting of the fog light might need to be made, however, I do not have a how-to on the because mine were almost perfect. There is a nut on the back of the foglights that you have to turn to adjust them.
Here are some pics of the finished product.
