Been searching the forum to see what it will take to do this upgrade. I have found a lot about replacing the third brake light with the camera, but I have an additional question. Hopefully someone may have some insight. My truck already has the bed-view camera in the brake light. Would I still need to take the whole headliner down to run the wires to the mirror, or might the wires be in there and just need to be connected to the new mirror?
I'm really hesitant to start taking the truck apart. I want to do a speaker replacement too.
Thanks in advance!
