Does anyone know how to hook up the 12v constant power to the run lights in my trailer? They definitely work on our dodge 3500, but on my 2014 Sierra 1500 they don't. My only assumption is its not hooked up from the factory. Is it as simple as the older model GM trucks? Hook up a wire to the post by the fuse box and plug in a fuse for that location? Cheers
2007 Silverado Trailer Light wiring
Swampthing posted a topic in 1999-2013 Silverado & Sierra 1500I am looking for information about the wiring on my 2007 silverado. I have lost my parking lights on my trailer so I have been trouble shooting and found that I am only getting 2.5 volts to the connector. I am also seeing a short to the frame ground (200Kohm) I started tracing wiring ( I travel gravel roads daily so I am looking for damage) I found a junction box ? on the frame between the box and frame above the gas tank where the wiring passes thru is this a splice point ? connector in there that could be bad ? it will be alot of work to get to it. Ideas ? Jeff
