Now if you look on your ballast (the main unit), you should have a few wires coming out of it.
Connect the wires coming from the bulbs to the ballast. Mine were blue/red with different connectors so there really was no way to screw that up
Now, there should be another pair of wires coming out of the ballast that looks similiar to this:

There will always be a black wire, and 99% of the time the other will be red. That's not so important, just the black wire is. This is the negative wire.
Look at the black plastic harness coming from the headlight housing, the original one that you took off of the original bulb. Notice there are two connectors, one has two wires, and one has one wire.

The one with two wires is the negative, and the one with one wire is the positive. THIS IS VERY IMPORTANT AND DO NOT REVERSE THE WIRES!!!!!
Insert the black wire coming from the ballast into the slot with the two wires.
Insert the red wire coming from the ballast into the slot with one wire.
Go into your car and turn the lights on to make sure it works okay. This now leaves you with two options.
You can unplug the wires coming from the vehicle harness (black and red / negative and positive) and take a razor blade and slit two slits in the rubber cap. Feed the wires coming from the ballast into the housing, connect them, and then shove all the wires into the housing and put the cap back on. It makes it really easy to put the rubber cap back on and it will never fall off. I had this method done until I got new headlights from the dealer.
Or, you can try to force the rubber cap on with the wires in the way. I do not really prefer this method, but I do not know if I want to slit my only pair of rubber caps yet, as they are brand new.

This is what it looks like with the cap forced on with the wires hanging out. It is very hard to put the cap back on, and if not done securely / carefully the cap could fall off during normal driving.
Now you may want to know where to mount the ballast. This is virtually up to you. For the N/A crossfires, look at where I mounted mine. Where the Intercooler pump is on the SRT-6 there is a screw already drilled where you can put the ballast harness on and put a nut on. Refer to the picture for the exact location.
