Wiring Topper Brake Light
#1

For the topper, you need to pull the feed from the harness just for the camper... IIRC, there is a green wire that terminates in the harness somewhere either near the back of the cab or near the back of the bed... My memory fails me at the moment. The feed is there just for the third brake light on the cap or on a camper. Just have to find it. If you know of a good camper shop around, they may be able to tell you where it's at, or a knowledgable tech at the stealership might know.
