I had an issue where my toad left rear light would not work when using turn signal or emergency flashers. I traced the wires from the front of the toad to the back and even ordered a new diode at the rear light and still didn't correct the issue. Somewhere along the wire path whether at the coach or in the toad the signal wasn't being sent.

Huge kudos to @Buly as while we were at Ruidoso Motorcoach Resort together recently he offered to help me troubleshoot this. I already lost a set screw at one end of the cable and replaced it not long ago so my first word of caution to anyone with the blue ox blue cable is to ensure your set screws on both ends are snug. Buly then disassembled both ends of the blue cable to inspect the wiring. On one end the red wire was actually removed from the socket which I believe is what my installer wired up to keep the toad battery charged while towing (battery is disconnected in my toad for towing). Connections were rusty which is obvious/expected as it's not a water tight setup so he cleaned up some of the wires. After verifying all connections, cleaning, and securing I'm happy to report I'm back to 100%. Many thanks to Buly for going the huge extra mile in helping me with this. I considered trying a new cable when at a RV dealership on my travels out west but they wanted $120 for it so I passed. It's cheaper on Amazon for around $80 should anyone need a new cable. But the moral is to inspect your wire connections on both ends of this cable and also make sure your set screws are snug. We've all heard of toad fires, this very well could be a cause from what we observed.
