Don't go cutting into wires without looking through your manual and fully understanding what each one do. You could trip the theft mode in your truck and cause more damage than good. What i see most people doing with these kill switch is controlling the start and the fuel pump as well. Don't quote me on the fuel pump part. It would be a good idea to go to a tuning shop (or any shop you can think of) and see if they do installation on those type of things and pick their brains and see what goes into it. Good Luck!
