You may want to try the wireing diagrams in the back of a repair manual.
Or, you could just test them and find out for yourself.
Theres gotta be a ground, a power on (for when the car is on), an always on (to keep it set when you have the car off), and one or two more for the dimming functions. A multimeter should reveal everything.
