Installation of Tow Ready Brake Controller Adapter

This adapter plugs into the 6-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

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

• Why Is the Manual Switch Not Working On The Hayes Brake Controller, # 81741B
  
• 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. If that do

• How to Locate the Stop Light Wire for a Brake Controller on a 1990 Ford E-350 Van or Motorhome
  
• 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.

• 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

• Can the Breakaway Battery Charger on a Car Hauler be used to Charge a Large Winch Battery
  
• 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. The best bet for charging the winch battery is to
