I'm completely new to Jeeps, know almost nothing but I bought an 05 LJ and am just starting to play with it. I'm swapping out the factory radio and in that process am adding a rear view camera that attaches to the license plate frame. I figured I could run the wires from the camera into the drivers rear tail light and follow those wires up front and into the cabin to the back of the radio where I will plug it in. My problem or ignorance is that I don't know where to access that wiring harness, where do the tail light wires go and how do I access that, crawled under and didn't see anything obvious, do I need to remove a panel or some such thing? Thanks
