Curt Venturer Trailer Brake Controller - 1 to 3 Axles - Time Delayed
part number: C51110

Electronic controller activates electric or electric-over-hydraulic trailer brakes with a preset intensity when you apply the brakes in your vehicle. Power output and braking aggressiveness are adjustable. Includes LED display and manual override.

Features:

  • Brake controller activates trailer brakes with preset intensity
    • Signal is sent to trailer brakes when tow vehicle's brakes are activated
  • Adjustable, slide-bar power output control lets you determine the amount of braking force
    • Set to maximum when you travel through hilly terrain with a fully loaded trailer
    • Back off the power output when you tow a lightweight trailer
  • Sync setting lets you adjust the aggressiveness with which the brakes are activated
    • Get full power output faster by moving slide-bar switch forward to increase activation speed
    • Achieve smoother braking by moving switch in opposite direction to supply power gradually
  • LED display shows brake force output
  • Self-diagnostics function monitors trailer connection and checks for shorts
    • Status LED glows red if disconnect occurs
  • Built-in, slide-bar manual override
  • Quick and easy installation
    • No need to mount level like proportional brake controllers
    • Mounting bracket and hardware included
    • Plug-in, vehicle-specific brake control adapter (sold separately) can be used for certain applications to reduce installation time


Specs:

  • Application: trailers with up to 3 axles (6 brake assemblies)
    • Designed for use with electric or electric-over-hydraulic trailer brakes
  • Overall dimensions: 4-1/2" long x 3-3/8" wide x 5/8" thick
  • Limited lifetime warranty


Time-Delayed Braking

The Venturer applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Venturer. The controller then sends power out to your trailer brakes to activate them with an intensity set by you, at a rate determined by you. Both the amount of braking power (output) and rate of application (sync) can be adjusted to suit your preference, the road conditions, type of trailer, and size of the load. To determine which levels are best for your application, you must test out your towing setup and choose what feels best.


A time-delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, the Venturer sends power out in the same way, with the same gradual delay, no matter the braking situation. Although this delay always exists, it can be adjusted by changing the sync setting.


Built-In Controls for Adjustable Power

Curt Venturer Controls and Components

The above diagram shows the controls and components of the Curt Venturer trailer brake controller.

  1. LED display
  2. Power output control
  3. Sync control
  4. Slide-bar manual override

Output Control

During the initial setup process, use the slide-bar control on top of the Venturer to adjust the output. The output control lets you set the maximum amount of power that will be applied to your trailer's brakes. Typically, the output is only readjusted when you experience changing road conditions or if you switch over from a heavy, loaded trailer to a much lighter, empty trailer, or vice versa. To get more power to your brakes, slide the switch to the right. To decrease the power output, slide it to the left. The bars on the LED display indicate the output setting from 1 to 8.


Sync Setting

To adjust the aggressiveness of your trailer's braking action, use the slide-bar control on the side of the Venturer to change the sync setting. If you want to reach maximum power output faster, move the switch forward. To get smoother braking action, slide the switch backward, thus supplying power to the trailer brakes more gradually. You can alter the sync setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.


Quick, Simple Installation

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. As a result, mounting options are limitless, so long as you can still easily access the controller.


Installation of the Venturer requires that you either purchase a custom wiring adapter designed to plug into the controller or that you hardwire the controller directly into your vehicle. To hardwire the Venturer, you must remove the plug at the end of the integrated wiring harness.


Installation Accessories

For easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.


Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6-brake applications

Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In
part number: C51451

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

Features:

  • 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 built-in port 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.


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


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.

When used with part number C51515, easy install, hardest part of install is deciding where to drill into your new vehicle's dash to mount controller, or just ask your wife :). The included test light makes finding the correct "cold" brake wire a breeze. 82283

easy install, but extremely hard to adjust trailer load setting cannot stop trailer from over braking, very hard to drive in traffic. if this is not a defective I would not recommend it 574025


Comments
The brake controller has two adjustments. You can adjust both the amount of power delivered to the brakes, and the speed at which that power is delivered. The synch control is located on the side of the controller, try decreasing the aggressiveness of the brakes a bit and see if that helps. Finding the perfect setting for the smoothest possible braking action could take some fiddling around with both the power and the speed adjustment.

Didn’t use do to lack of wiring that it doesn’t come with. Was looking for more of a plug in and go. Used a different product will try to use this on a different vehicle. 545769


Comments
This brake controller isnt a vehicle specific item. The wiring pigtail is the vehicle specific portion, and because the actual plug varies from vehicle to vehicle, the vehicle specific plug is sold separately. Most full and mid-sized pickups and SUVs manufactured since around 2000 will have the factory supplied connector for installing a brake controller.

Sorry for the late follow-up. I just wanted to let you know that the brake controller and wiring harness I purchased through eTrailer worked very well with my 2008 Dodge Ram 2500 with the Cummins 6.7L diesel. Pictures are attached for your use, as required. The trailer was an 18-foot enclosed snow machine tailer with a steel chassis. I can't remember the empty weight, but it's substantial. We towed empty and full on dry and snow covered roads from Oklahoma to Colorado and back. Even with th exhaust brake on my truck, I can't imagine towing this load through the hills and mountains without a brake controller. It's been done before, but I would say it's an unnecessary risk given the more than reasonable prices at eTrailer...it was cheap insurance pulling such a heavy rig with my family on board. The controller was definitely not your top-of-the-line model, but the adjustability and controls were more than adequate for somebody who tows occasionally. A professional may desire more proportional controls and adjustability, but not much more. This unit peformed flawlessly. Thank you for your time. Please feel free to contct me if you would like any clarification on my statements or pictures. 121176

The adjustments are too sensitive. It does nothing or it locks up the brakes. The unit in my other truck had a digital readout. I will replace it with a better unit. I think Curt is a good product, I just should have bought a better unit. 558307


Comments
Have you tried adjusting the sync control on the side of the brake controller? Pushing the control toward the front of the vehicle makes the brakes more aggressive, pulling it towards you makes them less aggressive. Id recommend lowering the aggressiveness, which should provide the results youre looking for.

Received product very fast. Everything I ordered was exactly what I got. Plug and play with what i ordered. It was hooked up with in less than 2 minutes then a couple minutes to screw in the bracket screws. Very pleased . I needed trailer brakes because I bought a camper and I did not want to wear out my truck brakes faster than normal. I looked around locally and on internet Etrailer had the best deal . 552650

The CURT Venturer brake controller works as described in the user guide. It would be better if the display LED segments were bright enough to see in bright light. My installation is different from most. I mounted the brake controller and a trailer 7-pole socket to my Trailer Valet with a magnet and use the controller to operate the electric brakes on my trailer. This is far better than relying on the Trailer Valet brake alone, especially when moving the trailer on a grade. 557200

Comments
after 8k miles of towing with this controller, I wish I had bought a better one. the controller works fine, but is hard to keep in adjustment. one day it works fine, and the next its applying too much, or too little braking. If you plan on doing a lot of towing, buy a proportional controller.

Thanks for your follow up and reply. I agree with you the proportional brake controllers are much better, especially for frequent towing. Our best selling ones are the Tekonsha P2 # 90885

and the P3 # 90195

  • Parts Needed to Install Curt Venturer Brake Controller in 2018 Ford F-150 with 7-Way
  • To install the Curt Venturer brake controller part # C51110 all you need is the install harness part # C51436 that you referenced.

  • Flashing Red Signal With Curt Venturer Brake Controller
  • If your Curt Venturer Trailer Brake Controller # C51110 is flashing red that means there is a short on the brake circuit of your 2002 Dodge Dakota. Since the controller is new and your trailer brakes work on your buddy's truck the problem is likely going to be corrosion in the 7-way of your '02 Dakota. You can try and clean it or, assuming you have the factory 7-way, replace it with the Multi-Plug T-One Connector Assembly for 7-Way & 4 Pole Trailer Connector # 20135. It is also vital
