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

Universal Wiring Adapter for Curt Trailer Brake Controllers
part number: C51515

This wiring adapter is designed for vehicles that do not come equipped with a factory brake control wiring harness port. One end plugs into your Curt trailer brake controller while the other end splices into your vehicle's wiring.

Features:

  • Universal wiring adapter eases installation of your electric trailer brake controller
    • No need to wire brake controller directly to your vehicle
  • Wire end splices into your vehicle's wiring
    • Use on a vehicle that does not have a factory tow package or on one that has a brake control harness but is not equipped with a plug-in port
  • Connector end joins with the plug on your electric brake controller
    • Compatible with time-delayed and proportional brake controllers from Curt
    • Simple to plug and unplug control for removal
  • 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. Usually when this is done, a port is installed at your dash so that you can easily plug in a brake controller. However, if no port is present, you will have to splice into your wiring.


With this universal adapter, you can install your Curt brake controller without having to wire the controller directly to your vehicle. If your vehicle has a factory tow package, just splice the pigtail end of the adapter into your vehicle's factory brake control harness wiring, and then plug the other end of the adapter into the controller. If your vehicle doesn't have a factory tow package, you'll have to hardwire the pigtail end of the adapter into your vehicle's wiring. Because only the adapter is hardwired to your vehicle, you can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.


If your vehicle is not equipped with a factory tow package, you will need to purchase additional equipment to ensure that the signals from your brake controller are sent to your trailer's brakes. We recommend etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately).

Product was easily located on website and was exactly what I was looking for. I had forgotten to take off of my old vehice before I sold it, so this allows me to plugin my Curt brake controller without having to cut the connector off of it. 570389

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.

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.

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

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.

Not much to say about this. Is what it is. Plugs in to the curt triflex brake controller nice and firm. A little longer (it’s about 2’ long) than I needed in my 2011 Silverado but the excess wire tucked away nicely. 614612

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

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

seems to work great, just right for my small single axle trailer. 122699


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

this went into my VW Touareg which requires the relay modification described in the Technical Bulletin. Because ground and +12V is already present in the harness, instead of running additional cables, I soldered the relay right into the cable, making it a clean plug and play setup which is 100% removable. I also bought the VW housing and wire kit to complete the install 116584

Wiring up a brake controller can be tricky. Routing the wire from the hitch to the firewall and finding the right wire on the brake are the hardest part, but etrailer will do their best to help. Consider running the wire inside the car along the door bottom just under the carpet. This avoids problems with the tie-wraps under the car -- there just isn't anywhere to tie wrap under the middle of the car. Use "loom clamps" ordered separately to solve this problem, if you go under the car. To find the right brake wire without cutting insulation, use the fish wire from the hitch install to contact the end of the wire inside the connector (from the back). Then touch the fish wire with the continuity tester and apply the brake pedal. My brake had a four wire connector and I found the right one on the second try. If you find a hole in the firewall with a rubber plug in it, don't discard the plug. Make a short slice in it with a razor blade and push the wires through. You may have to work the wires around to get them through the carpet. Be patient. Be sure to watch all the videos and allow plenty of time, taking a break before you tackle the hard parts. Rest assured that doing it yourself is better than allowing UHaul to cut corners and charge you labor. :-) If you are doing the hitch install and four-wire harness, those are much easier. If you are installing the hitch alone, be sure to have a magnet wand for when you push the bolt up into the frame rail. If I had it to do again, I would use a little electrical tape to hold the bolts down so a slight bump wouldn't knock them up. 257414

Ive not had any trouble with the hitch or the brake controller. I can tow my tear trailer anywhere I want and the hitch protects my mufflers from damage when I go offroad. Nice extra benefit.

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

I own a 2008 Chevy Silverado. I ordered the brake controller - C51515 and the universal wiring adapter on Friday and received it on Tuesday. My friend who is a mechanic installed it in about an hour on Wednesday. I towed my camper trailer to Lincoln, NE (about a 5 hour trip) on Thursday and returned on Sunday. After reading the settings instructions, all stops were made smooth and firm. Etrailer.com was great and the Curt Trailer Brake Controller is excellent! 104632


Comments
I have enjoyed the use of the electric brake controller. The stops are always safe and smooth. Im glad I got it for my truck and Ive never had a problem with it. I just need to get out and use my camper more! The initial contact with etrailer.com was very favorable and I will do business with them again when I need something for my trailers or tow vehicles.

This is my first experience with installing and/or using an electric brake controller so I'm by no means an expert. However, the Curt Venturer was easy to order and etrailer.com noted other parts I would need to complete the installation and use the product. It was delivered in a timely manner and was exactly as specified. I had my mechanic do the installation on my 1998 Nissan Pathfinder and it took him a couple of hours because of the age of the vehicle. The controller is easy and intuitive to set up and use and it works well. I will keep etrailer.com on my list of go-to places for my towing needs. 143219

Great brake controller, very small in size but works great. Ordered with the plug and play wire, hooked up in minutes. Was ordered for a brand new vehicle and didn't want to drill any holes in dash. Wire was long enough to just let the controller lay on the center console since it's a time delay controller and doesn't need to be facing any certain way. When not towing, the controller gets unplugged and stored in the glove compartment while the wire is stored under the dash out of the way ready for the next adventure. 653444

Excellent controller for my needs...fast shipping and a great price too! I read up on Progressive vs. Time Delay controllers; and for my needs I felt this Curt controller would be just fine. I just finished installing and adjusting the controller this morning. We recently bought a '99 Coleman Westlake Pop-up that weighs about 2,400 lbs. dry (much less than my brake-less boat trailer) and wanted to take advantage of the brakes that came on the camper for when we travel in the SC & NC mountains camping. On level ground I have found the controller to be very responsive and easy to adjust. I am sure having working brakes in the mountains will be nice! As others have said, finding just the right place to mount the controller was the most difficult part. The "plug & play" adapter/harness was more than long enough to complete the installation. Oh, did I mention fast shipping too! I am another very satisfied etrailer.com Customer! 402072

  • Installing a Brake Controller on a 2004 Dodge Ram Without a Factory Tow Package
  • We have everything you need to install a brake controller on your 2004 Dodge Ram. Since your truck does not have any factory trailer wiring, we will want to install a trailer connector first because the brake controller will tie into the trailer connector, vehicle battery and the vehicles stoplight switch. You will notice 4 wires on the back of your brake controller. The black wire is for 12 volt power from the vehicle battery via a 30-amp circuit breaker. The white wire should be grounded

  • Do Brake Controllers have Constant Power or Do they Wire Into a Ignition/Accessory Power Source
  • Brake controllers such as # C51110 will have constant power once installed. They need to have constant power otherwise they would reset every time you turned off the vehicle. Brake controllers have what is basically a sleep mode. After a certain amount of time the "go to sleep" and draw only a few milliamps of power so they will not drain the vehicle battery. If your 2007 Dodge Ram did not come with a factory 7-Way trailer connector then you will also need wiring harness # C51515 for

  • Wire Gauge For Installing Curt # C51110 Venturer Brake Controller on 2013 Santa Fe
  • When we do a hardwire brake controller installation here at our facility, we always use 10 gauge wire to carry the brake output circuit from the brake controller to the trailer connector. A 12 gauge wire is smaller in diameter which would increase the resistance and could make the wire overheat. I spoke with my contacts in the Tech Services departments at Curt and Tekonsha, both of which recommend using 10 gauge wire, and would discourage using anything smaller. We offer a brake controller

  • What is Needed to Install Curt Venturer Brake Controller in 2007 GMC Sierra New Body?
  • If you have the factory 7-way on your 2007 GMC Sierra New Body you can install the Curt Venturer Trailer Brake Controller # C51110 with just the Universal Wiring Adapter for Curt Trailer Brake Controllers # C51515. Should your truck not have a factory 7-way you will still need the adapter, but you will also need to add Connector # PK11898 or, if your Sierra has a round plug with a cap instead of a bundle of wires above the spare tire, use part # 30955 instead. There is going to be a

  • Brake Controller Installation on 2014 Ford E350 Van
  • The vehicle is unlikely to have the connector behind the dash unless it has the factory equipped 7-way on the rear bumper. If it does, the connector that the controller would plug into is clipped to the rear of the small cubbyhole or coin tray in the dash. You'll access the connector by removing the coin tray. If the van doesn't have the factory 7-way, you'll need to hardwire the brake controller using our Install Kit, part # ETBC7. If your vehicle is a motorhome on a van cutaway chassis,

  • Troubleshooting Curt Venturer Electric Brake Controller Doesnt Show Anything with Brake Pedal
  • It sounds like you have a short in the 7-way connector. I would start by cleaning it, if you haven't already, and possibly replacing it. Start by testing for power on the red wire going into the controller. It should only show power when the brake pedal is pressed. If it isn't then it's connected to the wrong wire. If the red wire checks out try testing for power on the blue wire coming from the controller. Since the controller's display isn't showing anything I doubt you'll read

  • Brake Controller and Install Harness Recommendation for a 2006 Jeep Commander
  • The correct Curt brake controller install harness you will need for your 2006 Jeep Commander is the part # C51515 that you referenced. I would recommend you go with a proportional brake controller with it like the Curt Triflex part # C51140 as it will sense the amount of braking you are applying with your vehicle and will provide a proportional amount of braking power to the trailer. Some models will require a wiring kit to run wire to the battery. This may require drilling a hole

  • Troubleshooting Curt Brake Controller Installation in 2007 GMC Sierra New Body Style
  • First I suggest making sure you are testing the brake circuit pin on your Sierra's 7-way trailer socket. If you refer to the linked photo of a trailer connector you will note the brake controller's output is carried on the pin at the 5:00 position; the ground is at the 7:00 position. If you happened to test the 12V auxiliary power circuit, carried on the pin at the 2:00 position, it will have power at all times. I see that you purchased Curt Universal Wiring Adapter # C51515 which

  • To install the Curt Wiring adapter # C51515 in your 2008 Chevrolet Silverado you will need to hardwire it under the dash. To be sure that the wire bundle you found under the dash is the correct set of wires I would check the white tag for any indication as to what each wire is for. If none of them have labeling then it would be best to test their functions with a circuit tester like part # PTW2979. You will then connect the following wires from the Curt adapter to the following functions: Blue

  • White Ground Wire Is Taped To Orange Wire 2009 GMC Sierra 1500 Brake Controller Install
  • You want to use the white wire in your photo for the ground. The other orange wire is the CHMSL circuit which stands for center high mount stop light wire. It is not used by a brake controller so you can tape it up and stow it out of the way. You will need 4 wires to install the brake controller, 12 volt power (red and black in your photo), trailer brake output (solid blue in your photo), stoplight circuit (light blue with stripe in your photo) and ground (white).

  • Troubleshooting Curt Venturer Brake Controller Installed on 2011 Dodge Ram 1500 Pickup
  • Getting a single green LED on the display indicates that there's no trailer connected. Since you're getting this with the trailer connected, it would seem to indicate that the brake controller isn't 'reading' the trailer for some reason. The most common reason for this to happen would be a dirty, corroded or damaged connector on the vehicle or the trailer. Examine the trailer connectors, and ensure everything is clean. If you see any white or green corrosion on the pins or sockets of the

  • When Does Brake Output Circuit of Vehicle 7-Way Have Voltage
  • The brake output circuit on a 7-way (5:00 pin) will only have as much voltage on it as the brake controller is sending. Typically this going to depend on the amount of gain selected on the controller and other factors like brake controller style and ramp up speed of the controller. The only time the circuit would have voltage without the brake pedal being applied would be if you had the manual override lever of the controller slid.

  • Installation of Curt Brake Controller on 2009 GMC Sierra 1500
  • When it comes to installing a brake controller like the Curt # C51170 using the adapter # C51515, the color of the wiring isn't always a reliable way to determine the functioning of a wire, so you'll likely want to test the functions using a circuit tester like the # PTW2993.

As long as you're able to match up the correct wires under the dash to the adapter, you'll be able to use the brake controller without issue. We
