Installation of Tow Ready Brake Controller Adapter
This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.
To install your electric brake controller you need to connect the four wires - ground, power, brake switch and brake power - of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If you do not have a harness, or you need a new one, the Tow Ready wiring adapter will serve the same purpose.

- Hayes Energize Brake Controller only Sends Full Power with Manual Slide and not with Brake Pedal
- The Hayes energize brake controller is adjustable. When using the manual slide, it will light brightly because it sends full power to the brakes when you slide the lever all the way over.
There is a pendulum sensor inside that detects how hard or soft you are braking. There is a little white or light colored arm on the left side of the controller. You need to align it with gravity, in other words, it needs to point straight down. Other wise the sensor will be off and will either brake too ha

- On the Hayes Brake Controller, # 81741B, if the manual slide is not working and the brake controller is wired properly, then you will want to slide the manual slide back and forth maybe 10 to 15 times to try and get the dirt or dust that might be built up between the slide and the metal strip that is inside the controller.
We have seen that happen before where something will get between the manual slide and the metal contact strip and prevent the slide from making a connection.

- I would be happy to explain how to set up the Hayes Energizer II Brake Controller, # 81741B.
First, park the truck and trailer on a dry level surface. Next, adjust the gain wheel to the middle setting. Then, you will need to travel at about 25 miles per hour or less and step on the brakes like in a normal breaking situation. The red indicator light should light up from dim to bright during the stop and revert back to dim after the stop is completed.

- To find the correct wire, you will need a circuit tester like the Quickee # 3808. Probe the wires on the brake switch located above the brake pedal. You are looking for the wire that carries a signal ONLY when the brake pedal is pressed. If the wire carries a signal at any other time, like when the vehicle lights are on or the turn signal is engaged, it is not the correct wire. I have included a link below to an FAQ article on installing a brake controller from scratch that may help.
view full answer... - Is a Battery Isolator Needed for 7-Way Wiring Installation
- The 12-volt power source at the 7-way connector is typically protected by a 40 amp fuse or breaker. This circuit is usually tied directly to the battery, with the fuse or breaker installed inline. This circuit is not isolated. Because this circuit can remain live even when the ignition is switched off, we recommend unplugging the trailer when the vehicle is not running to avoid the battery from being discharged. If you wish to avoid this problem altogether, using an isolator like part # TR118665

- Using the breakaway battery charger to charge another battery on the trailer is not recommended. The larger battery you are using to operate the trailer winch would take an extremely long time to charge with a breakaway charger and would likely never charge fully with the limited amount of time the trailer is connected to the vehicle, even if towing long distances. The breakaway battery may not be charged sufficiently in this situation either.

- This Hayes-Lemmerz Energize III Electric Trailer Brake Controller, part # 81741B, will not activate your brake lights with the manual over ride switch. The reason for this is based on how this controller is wired to your vehicle.
This controller taps into your brake light circuit and uses that signal to tell the brake controller to begin applying the trailer brakes. When you apply the manual override lever it will not put a charge onto the brake light circuit of your vehicle and activate your

- It sounds like the problem you are experiencing is due to a bad or incorrect connect on the red wire on the brake controller. The red wire attaches to the stop light wire on the brake switch. Using a circuit tester like # 3808, find the wire on the brake switch that carries a signal ONLY when the brake pedal is pressed. If the wire carries a signal at any other time, like when the lights are on or turn signals engaged, it is not the correct wire.
