- Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In

Install your Curt electric trailer brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the junction box beneath your 's dash.

  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • No cutting or splicing required
    • Custom connector end plugs into the electric junction box beneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from Curt
    • Brake controller must have built-in plug for adapter to connect - will not work on controllers with pigtail wiring harnesses
  • 2' Long, 12-gauge wires have protective covering to deter damage
  • Limited 1-year warranty


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.

First, let me say that I have never been disappointed with any of my transactions with etrailer. This holds true with my latest purchase of a Curtis brake controller and pigtail. This is my second because the first was fried when the trailer wiring shorted out. I received the controller in 3 days, which included a partial weekend. The pigtail make installation so simple. I literally had the old controller out and the new one in within 5 minutes. I will look at etrailer first for any of my trailering needs. 455332

This was well worth the money. No. cutting required it was fast and easy. Come to find out I had an universal type one that came with my truck but it would have required me to cut wires. But the universal one did have a fuse that is needed to have the trailer brakes work. So keep in mind you may need to buy one of those. I assume they are cheap but just another step in having it work! 386422

Bought this trailer controller cable with a Curt Trailer Brake Controller. I dont know if it works or not. I installed this along with thr trailer brake controller at the same time. Nothing works. No lights power up on the controller. I highly respect Curt Products as I have many installed on my truck, but I'm disappointed with this combo purchase. 386251

Appears to be the correct harness as the plugs match the brake unit and the splice in GM pig tail that came with the truck. Bought it to avoid cutting and splicing as well as avoiding voiding the brake unit warranty. Big Benefit also that I can unplug and move to another vehicle if needed Had the unit within 5 days including the week end, that's great customer service by etrailer 348216

The Curt electric brake controller was the easiest installation I have ever had. I ordered the custom wiring adapter along with the brake controller; it all came with easy to follow instructions and it only took about 30 minutes to install the entire unit. I had done some checking around to get estimates from various companies which do the installations and their costs were around $300.00. The Curt unit including the adapter wiring was $**.00 and a very easy install. I used the brake controller during a recent camping trip on which I was pulling a 24 foot camp trailer. The controller worked great and I could easily control the trailer in some extreme mountainous terrains in Wyoming. 277267

Only rating as good because I am concerned about the statement in the instructions to not mount the controller near any rf source. I happen to be a ham radio operator. Will be interesting to see if I run into any issues. I would have researched prior to buying but I never saw any info stating this might be an issue. I will have the controller mounted about 3 feet from a transceiver. We'll see. Now I will say that installation was a snap. Instructions clear and the included cable went right in. No problem at all and the controller seems to work fine. 215518

  • Wiring Adapter Needed to Install Curt Venturer Brake Controller C51110 in 2006 Silverado 1500
  • To install the Curt Venturer trailer brake controller # C51110 in your 2006 Chevrolet Silverado 1500 you will use wiring adapter # C51352. This part plugs in at the back of the controller and at the port under the dash as shown in the linked installation video.

  • Can Curt TriFlex Trailer Brake Controller # C51140 Be Temporarily Disabled When Backing Up
  • I did some research on this controller for your 2006 Chevrolet Silverado, and there are no features available that will turn the Curt TriFlex Brake Controller, part # C51140 off. The best way to temporarily disable the controller when you intend to back up is to unplug the trailer. If you were to unplug the controller, it would have to be reset when it is plugged back in. I spoke with my contact at Curt and they strongly advised against doing this because if someone failed to reconnect...

  • Brake Controller Does Not Work After Installation on a 2005 Chevy Silverado
  • On certain year Chevy trucks there are additional connections that need to be made under the hood to make everything fully functional. I have included a link to an FAQ article to help you. Make sure that you are plugging in the harness into the spot on the top row, second from the left. The Curt harness you should be using is # C51352. With the brake controller plugged into the right spot and all the under hood connections made and fuses in place the brake controller should work just fine.

  • Curt Brake Controller Wiring Adapter for a 2006 GMC Sierra
  • We do have a plug-in adapter for your 2006 GMC Sierra, but the Curt # C51451 that you referenced is a fit for Chevy Silverado and GMC Sierra pickups starting in 2014. For your 2006 Sierra you want the Curt # C51352 instead. This adapter will plug into the junction box beneath your vehicle's dash as is demonstrated in the attached photos.

  • It sounds like the red wire in the wiring harness # C51352 was not in the correct place. Take a look at the picture I have included and make sure that the wires in your harness are in the same places. This is the end that plugs into the truck. It needs to plug in at the junction box under the dash, to the left. It will plug into the spot that is on the top row, second from the left. The wire functions are white for ground, black for 12 volt power, blue for output to trailer brakes,...

Such 7-way connectors are not compatible with the Curt TriFlex. It is critical that before installing the controller the negative battery terminal be disconnected to avoid potential damage to the unit. Also, the trailer...

  • Troubleshooting Curt Tri-Flex # C51140 Brake Controller Installation in 2006 Chevrolet Silverado
  • Thank you for your recent purchases from etrailer.com. The quick-connect brake controller adapter harness you purchased along with your brake controller, part # C51352, is the correct one for your 2006 Silverado. Brake controller installation in your truck, if it did not have a factory tow package, requires you to complete some electrical connections and install fuses in the engine compartment, at the power distribution box. Since you also ordered a 7-way, I will presume your truck...

The power distribution box is located under the hood, on the drivers side on the fender well. I have linked you to an FAQ article that describes how to install a brake controller on a 2003 GMC Sierra.

For a Curt controller you would use # C51352. For a Hayes controller you would need # HA81780-HBC. None of these harnesses come with a fuse. It is possible that you are referring to the factory brake controller wiring harness that is included with some vehicles. If that is the case then the fuse for the brake controller...

  • Will a Brake Controller Install and Work Fine on a Truck with an ABS Brake Light On
  • A brake controller like the Curt Venturer part # C51110 does not tie into the actual braking system of a truck like your 2004 Chevy Silverado so it would still work fine. As long as your brake lights are functioning properly on your truck a brake controller will function just fine since that is the only circuit it has to use to operate. To install this controller in your truck like the one you referenced all you would need is the correct install harness, part # C51352. I attached an...

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...

This product simply plugs into the port that is located in the junction box that is under your dash to the left of your steering column.

  • You have installed correctly all of the components you referenced. The # C51110, # C51352, and the # HM40975. The issue you are experiencing is that the tow package wiring under the hood of your truck hasn't been completed like you suspected. The blue wire will need to get run to the brake output circuit of the 7-way you installed. Since this circuit isn't connected to anything that means the 7-wires that are at the rear of your vehicle aren't all ran. You will need to run a length...

  • Troubleshooting Brake Controller Installation On 2003 GMC 3500
  • When checking the brake output circuit of a 7-Way there should not be 12 volts of power all the time. A Curt brake controller will have what is termed 'dead' voltage at idle. This means there is voltage but no amperage draw. You can test for amperage instead of voltage to see if that is the case. If so, then you do not have a problem. If you are showing amperage draw that would indicate a short somewhere or possibly a problem with the brake controller. For a Curt brake controller, and if...
