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.

• Brake Controller Recommendation and Installation on a 2003 GMC Sierra with or without Factory 7-Way
  
• I did a little research and found that the Dexter Predator, # 58-8, is for 2 to 4 brakes. So if each wheel on your two axle trailer has a brake assembly, or just two of them, this brake controller will work. Brake controllers are not vehicle or trailer specific, so you will be able to use the best one for your application. I recommend going with a proportional controller because they offer the best and safest braking, and will reduce wear on both the trailer and tow vehicle brakes. I have inc

• Brake Controller Does Not Have Full Power When Used
  
• First, I would go to the 7-way connector and test to make sure you have power. You will want to use a circuit tester, part # 3808 to test the wires. Start by testing the Black wire for power, then test the Blue wire for brake controller output. To test the Blue wire you will need to have a friend help you. With the vehicle in power accessory mode, in park, and parking brake engaged, have them activate the brakes. Next I would check to make sure the Red Stoplight wire is connected and function

• Hazard Lights Locking Up Trailer Brakes and Activating Electric Brake Controller On RV
  
• If the red wire from your brake controller is tapped into a wire that has voltage when the hazard lights are activated then this situation will occur. You will need to attach the red wire from the brake controller to a brake signal wire, under the dash at the brake pedal switch, that only has power when the brake pedal is pressed on your RV, so that when the hazards are on your trailer brakes do not lock up.

There are different kits depending on whether or not the vehicle has a trailer connector or not. If your van has a 4-Way trailer wiring harness, you will need to use the 4 and 7 way installation kit # ETBC7. It comes with the 7-Way, wiring, and accessories to wire in the brake controller.

• Location of Brake Controller Connector on 2013 Ram Truck
  
• The connector you are looking for will be located taped to another larger wiring harness just to the right and above the emergency brake pedal, as shown in the photo I have edited for you. You can confirm that this is the correct connector by testing it with a circuit tester like part # 40376. One pin should show a constant 12-volt power supply, another should show voltage only when the brake pedal is pressed. Unfortunately, my contact at Tekonsha was not able to shed any light on why the

• The light blue wire mentioned in the video of the # HM40975-11998 7 and 4-pole trailer connector being installed on a 2002 Silverado is for a camper shell brake light, and is not for use with an electric brake controller. The electric brake wire on your 2001 GMC Sierra is run from the port below the dash into the engine compartment, but it does not continue back to the rear wiring bundle. You will need to finish the connection by running a wire from the 7-Way in the rear of the truck up to t

• Amperage Capacity for Power Wire on a Factory 7 Way on a 2009 Chevy Suburban
  
• Typically, the power wire on a factory 7 way is on a 40amp circuit with a fuse or breaker somewhere near the fuse block. Sometimes it can be a 30amp circuit. If you are going to be running more than 30amps, I would call the service department at the dealer you got it from and find out for sure. You could also give the fuse block a quick check to see if it is clearly identified.

• Right Turn Signal on Trailer Towed by 2004 Chevy Trailblazer Not Functioning
  
• On a 6 year old vehicle, there might be a corrosion issue on the trailer connector. Can you see any green corrosion on any of the pins in the connector? If so, the corrosion might have spread to the interior of the connector preventing the signal from getting through to the pin.

• Brake Controller Adapter Incorrectly Pinned Out on 2003 Chevy Silverado
