Supplemental Brake System

Towed Vehicle Breaking.100% Proportional Braking.100% Hassle Free Tow Brake System for every car and motorhome. 

The Supplemental Brake System uses the electrical connections already in place on your towed vehicle (the towed vehicle's electrical harness) to brake when you brake the
motorhome — the same electrical signal that activates the towed vehicle's brake lights also activates the Supplemental Brake System.
