The Patriot actuates the toad's brakes through a proportional inertial system. The sensitivity of the actuation is remotely adjustable from the RV. The remote indicator tells you when the brakes on the toad are being actuated, and allows you to adjust the sensitivity setting.
The lights in the toad are another matter. My installer refused to cut into the wiring harness for the toad stating concern for the sensitive electronics that it has. Instead he installed separately wired LED bulbs in the rear light housing that are wired up to the RV. Also as mentioned elsewhere here, when the Patriot pushes on the brake pedal, the normal stop lights for toad are actuated.
