Just for those who don't know..
The '05's up use The H13 its quite possibly the stupidest design for a bulb ever foisted on the public. The terminals are so small that they overheat, even at stock wattages, and melt the plastic housing of the connectors. Higher than stock wattage bulbs are offered, but not recommended. There are Chinese connectors that are being used to make these kits and no harness will fix the problem of to small of terminals. As of now no USA made plugs are made that I have seen and wouldn't solve the problem anyway.
You have the best headlight housings made now and the addition of Hellas harness and a set of their 80/100w 4k kelvin bulbs will give you fantastic lighting.
You can also do a fog bulb upgrade..75% as bright as Hids and mod the switch to use them with your high beams.
There are kits available i which you replace the halogen bulb with a gas discharge bulb. The gas discharge light source is 2.5 times as bright as the halogen bulb and does not focus correctly within the headlamp, as the headlamp was not designed for this bulb. Hids require alinement withen 1/5000" or the will cause major light scatter. This creates excessive glare (up to 100 times), which blinds oncoming drivers, and is very dangerous and illegal in every state.
IMO anyone selling these this kits are just making a fast buck with no reguard for the outcome of their use.
