Installation of Curt Brake Controller Adapter

To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


Junction Box on VehicleBrake-Control Adapter Port

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.


No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

Video Transcript for Curt Brake Controller C51342 Review

Today we're going to review part number C51342. This is the CURT custom wiring adapter for the trailer brake controllers. This is the dual plug in design. This is a custom fit part number, it is designed to fit the 1999 to 2002 Cadillac, Chevrolet and GMC vehicles. This is a custom fit part so I would recommend to go to our website, use our fit guide and put in your year and model vehicle and it will show you if this part will work for your application. This is a plug-in wiring adapter, it allows for a quick, simple installation of your electric brake controller. There is no cutting or splicing required. You can see on one end is the custom connector end which will plug into your factory built-in brake controller port, usually beneath the dash of your vehicle, and the other end right here will plug into the back of your CURT brake controller. This is compatible with the time delayed and proportional brake controllers from CURT, I have an example here of a CURT Venture brake controller, you want to make sure that the brake controller must have this build-in plug for the adapter to plug into, it will not work with the brake controllers that just have pigtail wire harness come out the back. When you do go to the install this, basically you would just match this up, plug it, lock it into place and then you're ready to go.

You take this end and locate your factory built-in port brake controller on your vehicle, plug that in and your brake controller will be ready to go. When you want to remove it just push down on this and your brake controller removes right from the harness. This is about two foot long, uses 12 gauge wires and it has the protective wire loom over it to prevent any damage to the wires. That should do it for the review on part number C51342, the CURT custom wiring adapter for the CURT trailer brake controllers. .

I purchased a Curt brake controller from the Chevy dealership and when it arrived it was a controller and a hand full of wires to splice into my system. I got a hold of etrailers and the staff was pleasant and sold me what I actually wanted from the dealership. Now I know to call these guys for all my trailer wiring needs. 593806

This made installing my Trailer Brake Controller a breeze. I had a harness already that came with my truck, but would have to get the connector and pins to put on it to mate it up to the controller. This was already done and ready to go. 2 minutes time to installt he brake controller and have it ready to go. 86010

  • No Power to Trailer Connector on 2002 Chevy Suburban with Curt Trailer Brake Controller
  • On certain model year Chevy and GMC trucks and SUVs there are some connections that need to be made under the hood to make everything fully functional. It happens on vehicles with or without the factory tow package. Basically, it sounds like the power output to the trailer connector from the brake controller is not run. You will need to manually run it from where the wire terminates under the hood to the back of the 7-Way in the 7 oclock position. You can use wire # 10-1-1 sold in increments...

  • Curt Venturer Brake Control Applies Full Power to Trailer Brakes All the Time on 2000 GMC Sierra
  • The first thing to check is the wiring harness # C51342 for your 2000 GMC Sierra. Specifically, check the location of the red wire on the end that plugs into the truck. Make sure it is in the same location as the one in the picture. If not, or if any of the wires are in different locations, move them to the correct locations according to the picture. Make sure the controller is mounted within the range specified in the instructions, linked to the right for reference. If it is outside...

  • Troubleshooting Curt Brake Controller Installation in 1990 Chevy Silverado
  • If your brake controller is a time-delay type like the Curt Venturer # C51110 it should activate the trailer brakes either when you press the brake pedal or press the manual override lever. But if you have a proportional type controller like the TriFlex # C51140, which is triggered by inertia (from the motion of your truck) then the brake pedal will activate it ONLY if you are moving. With both types of controller the manual override lever should activate the brakes to the selected power...

  • Curt Brake Controller Not Working Correctly After Moving It From 2006 Silverado to 2001 Model
  • If you are using the same wiring adapter in the 2001 as you had in the 2006 Silverado, it would explain the problem you're having. Both model years use the same plug, but after the 2002 model year, GM changed the pinout on the connector under the dash. The 2006 Silverado uses the # C51352 wiring adapter, while the 2001 model would use the # C51342. I've edited a photo for you showing the difference between the two connectors, you can move the red wire to the correct location by removing...

  • Troubleshooting Curt Venturer Trailer Brake Controller on 2002 Chevrolet Silverado
  • It sounds like the wiring harness under the dash of your 2002 Chevrolet Silverado does not have power running to it. To test this, use a circuit tester like # 40376 to check the connector. If this is the problem, you will need a Universal Wiring Kit for Brake Controllers # C51500. The install instructions are attached. You'll also need to modify the factory harness in your truck a bit. On the factory harness cut the battery wire leading to the factory connector leaving enough room...
