Actually, this website is not limited to just the Challenger, it will provide wiring diagrams for any Chrysler.
You can input your VIN or choose the year/make/model/etc., and it will provide you with a menu of all available wiring diagrams. Then you can drill down to see what wires goes where, what color(s) specific wires are, and so on and so forth.
I do not remember how I originally found this link (was it from here? can't remember), but I found it hidden in my Linux box's browser's bookmarks earlier, and I was amazed at how much info it offers. So I figured I would make note of it here so that others may benefit from it as well.
