Here is an install I did of a DDM HID Kit. I've done 5 of these so far and we carried them all out to Oklahoma a couple of weeks ago to ride the dunes. Treated them rough and did lots of night riding with no issues. For $35 you can't beat them. Here's what you need to order:

Bulb Type: H6M (+$10.00)
Wattage: 35 Watt
Bulb Color: 6000K
Here's the wiring diagram I came up with to make it light one light on low and both on high.
Pull the plastics and remove the headlight assembly. Pull the boots back and remove the screws holding the bulbs in.
Cut the wiring to the sockets and pull the boots off the wires. (I leave enough wire to put them back later if I want.)
Install the new bulbs in the housing. Cut the wires on the extra harness and pull them out of the boot.
Cut the back out of the original boots from the bike. I use scissors.
Install the modified old boots over the new ones and they will seal up nicely.
Drill the mounting hole in the relays and mount them to the bolts that hold the oil cooler.
Mount the HID boxes somewhere you feel comfortable. I cut a mounting plate out of sheet metal and pop rivet it to the frame. Then I mount the boxes with 3M double sided tape and put a big zip-tie on for good measure.
Wire everything up according to the diagram and you're ready to go. I run the low side off the factory harness and I run a new wire from the battery with a seperate fuse to run the highs.
