Is there a single wiring harness available that would run the brake/rail lights, and power the brake system from the motorhome?

They all use the toads electrical system for power, for a very good reason. Should your toad break loose, the connection to your motorhome disconnects, and the braking system needs power to stop the toad. You should always use a breakaway cable. The standard is to wire the umbilical so when the toad is connected, and you are underway, the toads battery is trickle charged from the motorhomes electrical system. in over ten years of towing, using a U.S. Gear braking system, which uses its own vacuum pump, I never had a dead battery on the toad, or for that matter, even a weak one.
