If You already ran power into the b/u light switch then all you need to do now if there are 4 wires in your tail light harness is figure out which is the b/u light wire and splice your switch output into it. Its pretty easy to test by running a jumper to 12v power and checking to see if the lights come on. If they dont you can probe the center pin to verify power at the light socket with a test light.
