The Energize III Brake Controller by Hayes is designed to deliver smooth proportional trailer braking. Depending on the situation, it provides heavy-duty emergency braking, general braking, or soft and gradual braking for your trailer automatically. On the front the brake controller features a little thumb wheel for adjustable gain setting, which lets you determine the power output sent to the trailer brakes. For example, when towing on the bumpy road or when your trailer is fully loaded, you can set it to a higher output. When towing an empty trailer, you can set it lower. A deceleration sensor lever lets you adjust the braking aggressiveness.

A red LED indicator on the front of the brake controller shows when the trailer brakes are applied. Trailer and tow vehicle stoplights operate automatically when the manual lever or trailer brakes are applied. This brake controller has built-in features that provide for your safe towing. A current limiter protects your vehicle from shorts in the trailer wiring. It also has a hazard flasher immunity to prevent the pulsing of the brakes when flashers are activated. If you want to experience smooth, proportional braking every time look no further than the Energize III Brake Controller by Hayes.

Hayes® Hayes proudly manufactures electronic brake controllers to cover all towing needs. The first Hayes brake controller rolled out from the assembly line in the 1950's. The company has more than 60 years of experience in producing brake controllers. Hayes has withstood the test of time and still holds leading positions on the automotive market. By incorporating new technologies like the 'quik-connect' system, Hayes is able to stay on the forefront of intelligent brake systems. Hayes brake controllers ensure safe deceleration with extra weight behind your vehicle.

Hayes® 81741B - Energize III Brake Control
This is my second one the first one I used for almost 7 years. Worked great till I dropped it. So when I was at the store. Saw it and got it! With not a second thought about any other one. Currently use this with a 33' Travel Trailer with Tandem axles (4) brakes.
