Curt Venturer NEXT Trailer Brake Controller - 1-3 Axles - Time Delayed
part number: C74VV

A simple LED display and a pinch-trigger manual override make this time-delayed brake controller easy to read and easy to use. Installation is quick and simple with no mounting restrictions. Activates brakes with a preset intensity.

Features:

  • Brake controller activates trailer brakes with preset intensity
  • Adjustable power output control lets you select the amount of braking force
    • Rocker switches located on left front of module for easy access
  • 10 Gain settings and 9 load settings allow you to adapt to various driving conditions
    • Select a higher setting for harder braking and lower for more gradual braking
  • Pinch-trigger manual override is within easy reach for controlling trailer sway or stopping in emergencies
  • Simple LED display shows the amount of power output
    • Self-diagnostics monitor trailer connection and check for shorts
  • LCD display shows power adjustments in 1.0 increments
    • Brightness is adjustable for optimal visibility
  • Auto-sleep mode prevents battery drain after 5 minutes of idle time
  • Quick and easy installation with no mounting restrictions
    • No need to mount level - install anywhere at any angle
    • Included mounting bracket and hardware designed to hold brake controller flush against the dash
    • Plug-in, vehicle-specific brake control adapter (sold separately) available for select vehicles to reduce installation time


Specs:

  • Application: trailers with up to 3 axles (6 brake assemblies)
    • Compatible with low-volt, PWM, ABS, cruise control, and electric-over-hydraulic trailer brakes
  • Dimensions: 4" long x 3-1/8" wide x 1" thick
  • Limited lifetime warranty


Gain Adjustment

Gain control lets you set the maximum amount of power that will be applied to your trailer's brakes, adjusting in increments of 1. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. You want to go as high as you can without the trailer brakes locking up. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes. To get more power to your brakes, press the left-hand upper rocker switch. To decrease the gain, press the lower switch. When you make your adjustment, the gain setting will show on the LED screen for 5 seconds as a series of bars and then go into sleep mode to reduce drain on the battery.


Load Control

Once you have the gain set, you can fine-tune your braking by adjusting the load control on a scale of 1 to 9. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. Load control can get the braking power to your trailer faster and with more intensity so that it doesn't push your tow vehicle forward. If your vehicle takes too long to come to a stop, increase the setting by pressing the right-hand upper rocker switch. If it stops too abruptly, decrease the setting by pressing the lower switch. You can alter the setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.


Pinch-Trigger Manual Override

The Venturer comes with a easy-to-reach, pinch-trigger manual override, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just push in the trigger. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.


LED Display

The LED display on the Venturer is large and easy to read at a glance. It will show you what setting the brake controller is on as well as give you information for troubleshooting. You can adjust the screen brightness or trigger night mode so it won't glare obnoxiously on your dash. Press the control button to cycle through the different modes, shown as a bar - keeping it simple.


Curt Venturer NEXT

Quick Installation

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. Your mounting options are limitless, so long as you can still easily access the controller and the manual override. The included bracket is designed to mount the brake controller flush to the dash so it takes up almost no space at all.


If your vehicle already has a plug-in brake controller wiring harness, just connect the unit to it. Otherwise, you will need to purchase a vehicle-specific wiring harness (sold separately) to plug into. If a harness is unavailable for your vehicle, hardwiring will be necessary.


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- to 8-brake applications


See also etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.


Time-Delayed Braking

what is time-delayed braking

The Curt Venturer NEXT comes equipped with time-delayed braking. 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 (gain) and rate of application (load) can be adjusted to suit your preference, the road conditions, the type of trailer, and the weight of your load. To determine which levels are best for your application, test your towing setup and choose what feels right.

Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In
part number: C51525

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 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 harness is located underneath the dash, to the left of the steering column, and it is taped to another harness 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.

This is used on a 2020 Chevy Silverado 1500 pulling a 16' enclosed cargo trailer. With the appropriate adaptor cable it was very easy to install, just plug in and mount in a convenient spot. Once installed it was simple to get it matched to the weight and brake setup of the trailer. Close to 6k miles with it so far & very happy.



by: John 04/13/2024

Installed but not used with a trailer yet, easy instruction and appreciate the extra hardware for the installation.
Compact and not intrusive. Decided to use the adhesive tape included and taped under the dashboard L of the steering wheel.

Jon, what you will want to do is to take a multi-meter like the Item # PT29ZR and ensure you are getting power to your controller. You should be getting 12 volts on the black power wire and when you hit the manual over ride you will get 12v on the blue brake controller wire. If you are not getting full power you will have a loose connection somewhere and you will want to start at your fuse and work forward until you find it.

Do you have a question about this Trailer 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 # C74VV 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 install

  • Making Under Hood Connections to Power Brake Controller and 7-Way on a 2008 Chevy Silverado
  • Not all Chevy trucks have the tow package wires completely installed from the factory. This means there could be some connections you will have to make under the hood to power the brake controller and the 12 volt circuit on the 7-Way trailer connector. I have included a link to a how-to article that explains the under hood connections that need to be made. I am not sure which video you watched so I have linked another on a 2008 Silverado and a different brake controller that should

  • Troubleshooting Brake Controller Where Screen is Blank and Stopped Working
  • Most likely you blew a fuse if the brake controller screen one day stopped working. But that also depends on how the controller was installed. Basically the black wire of the brake controller needs to have 12 volts ran to it and the white needs to ground properly. If you can verify that and the controller still doesn't work though that would indicate the controller is bad. If it's a Curt Venturer # C74VV like what you referenced then I'd most likely think it's a bad controller as these

  • Flashing Red Signal With Curt Venturer Brake Controller
  • If your Curt Venturer Trailer Brake Controller # C74VV 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

  • Parts Needed To Install Curt Venturer Trailer Brake Controller 2023 Hyundai Santa Cruz Factory 4-Way
  • You will be able to install the Curt Venturer NEXT Trailer Brake Controller # C74VV on your 2023 Hyundai Santa Cruz with the Pigtail # C77BR. As you only have a 4-way flat you will need the Curt T-Connector Vehicle Wiring Harness # C68JR to install a 7-way on the rear of your Santa Cruz. A Mounting Bracket # C67UR is needed to secure the 7-way since there is not a bumper cutout like you find on most trucks.

  • Troubleshooting Curt Venturer Trailer Brake Controller With Brakes Always Locked On
  • The Curt Venturer Trailer Brake Controller # C74VV could be faulty. To find out for sure you can bench test the controller as per the instructions. I have included those below for you to reference. Before removing it for a bench test I suggest checking the red wire that runs to the brake switch. This should only show 12v power when the brake pedal is pressed. If the brake switch is faulty this would cause the brake controller to believe it needs to send power to the blue brake wire.

  • How To Install A Brake Controller On 2019 Chevy Equinox With Factory Package
  • According to Curt there is not a plug-and-play brake controller adapter for the 2019 Chevy Equinox so the Curt Venturer Brake controller would need to be hardwired in. To do this, you would need to convert the factory 4-way on the Equinox using a brake controller install kit part # ETBC7. The ETBC7 comes with all of the necessary components to hard wire the 7-way plug to the rear of the Equinox. Your existing 4-way plug will plug into the provided 7-way plug.

  • How Does Brake Controller Install in 2014 Chevy Traverse with Factory 7-Way
  • Your 2014 Chevy Traverse that has the factory 7-way does not require accessing the brake controller wiring if your plan was to install the Curt Echo Mobile brake controller part # C74VV that you referenced. Basically you'd plug in the Echo directly into your 7-way and once you've synced it to your smart phone you'd be ready to tow. If you wanted to install a more traditional brake controller like the P3 part # 90195 you'd use the install harness part # 3026-P which plugs into a gray

  • How to Find the Stop Light Switch Circuit on a 2013 GMC Terrain
  • The stop light switch circuit on your 2013 GMC Terrain that you will need to find to install the Curt Venturer Trailer Brake Controller part # C74VV will need to be accessed through the body control module (BCM). The BCM is located under the driver's dash above where your left knee would be.

  • Troubleshooting Curt Venturer Brake Controller Installed on 2007 Ford Freestyle
  • It sounds like there's too much going on with the controller for it to be a faulty unit.

Use a circuit tester like part # PTW2993 on the wire you have the red brake controller wire attached to. In the 2008 model, a purple/white striped wire was used, but I have no information about a 2007. This wire should show power ONLY when the brake pedal is pressed, not with the turn

  • Troubleshooting Constant 12V Power on Blue Brake Output Wire with Curt Venturer Brake Controller
  • If you are reading a constant 12 volts on the blue brake output wire with the Curt Venturer Brake Controller # C74VV installed, this is indeed an indication that either the controller itself is bad or there's a short somewhere along the brake output wire on your truck (between the controller and 7-Way connector). The first thing I recommend doing is severing the blue wire just a few inches behind the Curt Venturer and testing for power again on this wire. This will isolate the controller
