Message: [QUOTE="obs7.3, post: 346281, member: 4511"] I put in a LED third brake light and cargo light and had to splice it into the stock wiring in the roof. but whenever my truck is running the 3rd brake light is always on. it gets brighter when I step on the brakes. it's like i tapped it into the parking lights or something (but this is the only light that's on whenever the truck is running) but I checked the wires and there's just the 3 power wires and 3 grounds. i'm not sure if the stock third brake light did the same thing or not cuz the bulb was blown in it when i swapped it out but i never noticed it before the bulb blew. has this happened to anyone else? where could that harness in the roof to be getting power at?
