Back Up Lights Not Working

Please help if able:
My back up lights stopped working in both tail lights and cargo. Also, when my trailer is connected, the back up lights aren't working on the trailer. All bulbs are fine, all the fuses for back up lights in the cab fuse panel and the engine compartment fuse panel are fine. After I test the relay, assuming it is fine, then what? The backup camera is working fine. Brake lights and blinkers are fine. Is there a reverse light switch in automatic V6?

 

There is a reverse switch on your transmission. Recently have any work done? or do any hard wheeling? Just two wires connect to that switch and its a pain to get to. When my clutch was replaced, one of the wires were damaged and I found it fairly quick. My mechanic had to pull out my gear shift to reach it from the top. Mine is a standard transmission though. Maybe the autos are easier?

Here's a video for reference. Its a 2nd gen but its the same switch.
