An electrical brake control is a tool that delivers a signal from your own vehicle’s brakes through 7-pin hook-up on the hitch, to your truck. Your truck features brake system already, however they won’t work if you don’t install a brake control who is going to translate the indication. Think about the operator since the cardio of the truck braking system. All of the braking system outlines (veins and arteries) can move energy from your own pull vehicle, however they are pointless without the heart/controller to really pump/control that power.
