Roadmaster 156-75 Motorhome Charge Line Kit | Provides Efficient Battery Maintenance | Universal Compatibility | Self-Resetting Thermal Circuit Breaker

Had everything I needed to provide power to my towed vehicle (from the motorhome side). Don't know if the breaker works, which means I wired it correctly & would need to force a short & see if it does what it's supposed to do.

Kept battery on tow vehicle charged just fine!
