  • 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

  • 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

  • Location to Install Brake Controller Power Fuse on 2003 GMC Sierra
    I am assuming you are speaking of the fuse that activates the power feed to the brake controller. The 30 amp fuse is installed in the power distribution box as shown in the photo I have edited. 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.

  • Troubleshooting Curt Brake Control Harness # C51352 Installation in 2007 Chevrolet Silverado Classic
    The Curt Brake Control Harness you reference, part # C51352, is compatible with both time-delayed and proportional brake controllers from Curt and is intended for vehicles with factory tow package wiring. As you noted, the connection port for the vehicle-side connector is under the dash in the electric junction box. The box interior is shown in the photo provided; the correct connection port for the harness (the second one from left on the top row) is highlighted in red. There are one...

  • 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...

  • No power to New Trailer Brake Controller Install on a 2007 GMC Sierra Classic
    You will likely have to make at least one connection under the hood of your 2007 GMC Sierra Classic to power the brake controller. You may also need a fuse. I have included a link to the right that shows the connections that you will need to make under the hood to make everything fully functional.

  • 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...

  • Troubleshooting Curt Venturer Brake Controller
    Is this a new controller and harness? I was unable to find an order number from you to see if it was, but if so you may have connected the harness to the wrong port, as that is not uncommon for a Chevy/GMC from your model year. I have added a link to a help article detailing where you should plug in your harness, which is the second slot from the left on the top row of the junction box under the dash. Otherwise, if your brakes are not working when you use the Curt Venturer Trailer Brake...

  • Troubleshooting a Voyager Brake Controller for No Lights When Brake is Applied
    Have you tried testing the controller with the trailer connected and the truck moving? The vehicle needs to be moving for the controller to work.

  • Parts Needed to Install a Trailer Brake Controller on a 1997 Chevrolet C/K Series Pickup
    A brake controller wiring harness is not available for the 1997 Chevy K 1500 pickup. You will need to hardwire in a brake controller using 3 parts: a brake controller, a 4 and 7 way installation kit, and a 4-Way trailer wiring harness. If your truck already has a 4-Way trailer connector then you will not need to add one. But if it does not have any trailer wiring you will need to first install # 118315.

  • Comparing Tekonsha Prodigy P2 and Curt TriFlex Brake Controllers for a 2005 Chevy Silverado 1500
    The Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 with the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3015-P is what I recommend for a 2005 Chevrolet Silverado 1500 over the Curt TriFlex Trailer Brake Controller part # C51140 with the Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51352. The Curt TriFlex and Tekonsha Prodigy are both good options with similar features but the Prodigy is much more proven and has been around longer.

  • 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.

  • Trailer Brakes Will Not Work and 2006 Chevy Silverado Lights Malfunction w/Curt Brake Controller
    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,...

  • Fuse Location for Brake Controller on a 2005 Chevy Tahoe
    On your 2005 Chevy Tahoe, if using a Hopkins brake controller you would need connector # HM47795. If it is a Draw-Tite, Reese, or Tekonsha harness you would use # 3015-P. 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...

  • 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.

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...

  • 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...

    Yes, you have identified the issue as brake controllers are designed to work with their specific harness and not spliced into them, assuming you have the plug-in option. We do not carry the brake controller you have so I am not familiar with it, but for example on your 2003 Chevy Silverado if you had the Tekonsha PowerTrac Electronic Brake Controller # 39523 you would need to use the Tekonsha Plug-In Wiring Adapter # 3015-P.

    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...

    You may or may not need an additional wiring harness to install the brake controller. If your 2007 Chevy Silverado is the new body style you will not necessarily need the harness, but if it is a Classic you will need harness # C51352 because there is a port under the dash on the floor, on the far left. One end plugs into the controller, the other end plugs into the port. The port is located in a junction box. There is a black cover on the box. Remove the cover and plug in the harness...

    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...
