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: C51422

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.

  • Troubleshooting Brake Light and ABS Dash Light On After Installing Brake Controller
  • It sounds like you installed the red wire in the correct location, however the ABS brake light on your dash seems to contradict that. I recommend retesting the switch where you connected the red wire of your brake controller. There not only should be signal when you hit the brake, but there should be absolutely no other power when you use any other function of your vehicle. Check your blinkers, hazards, headlights, etc. Use a circuit tester like # PTW2993 to confirm proper function.

  • How to Set a 2012 Nissan Frontier Up for Towing a Trailer with Brakes

  • Troubleshooting Brake Controller Possibly Making Trailer Brakes Hot to Touch
  • You should be able to go all the way down to one bar on the sync setting so if your Curt Venturer # C74VV is stuck on three I would recommend unplugging it for a few minutes to let it reset and then try again. 3 bars wouldn't overheat your brakes though unless the brakes are applying all the time? Can you check the output pin of the brake controller circuit with a circuit tester like part # PTW2993 to see if there is voltage on that pin at all times?

  • Curt Venturer Trailer Brake Controller Installation in 2006 Dodge Ram 2500
  • Any trailer brake controller, including the Curt Venturer # C74VV, uses a 4-wire hookup. All brands and models of trailer brake controller have a white ground wire, a black 12V power wire, a red input signal wire and a blue output wire. The white ground wire connects to battery negative; the black power wire connect to the battery + terminal through a 30-amp circuit breaker or fuse; the red input signal wire connects to the cold side of the brake light switch above the brake pedal; and

  • Troubleshooting Brake Controller Installation in 2011 Chevy Silverado 1500
  • Since it seems the issue is on the brake wire, start by testing the brake controller. Sever the blue wire a couple inches from the back of your controller. Then use circuit tester # PTW2979 to test the end of the blue wire coming out of the controller. It should only have power when you apply the manual override; if it shows power at idle then there is an issue with the controller and it will need to be replaced. Additionally, because you otherwise have power with the stop light switch

  • Troubleshooting Trailer Brakes That are not Functioning Properly
  • This sounds like it could be one or two things. A short could definitely be causing the issue, but it may also be a ground problem as well. To start, reconnect the blue wire to the brake controller. This will take two people but using something like the Circuit Tester # PTW2993 you will need someone to run the manual override on the TriFlex # C24VV while checking the output on the 5 o'clock position on your 7 Way. This should be putting out 12 volts, or very close to it. When the manual

  • Troubleshooting Brake Controller Install 2003 Chevy Silverado 1500HD that Wont Work w Brake Pedal
  • Since your truck is a 2003 Chevy Silverado 1500HD you should check the third brake light fuse of the truck.

  • Is there a Direct Plug In Port on a 2011 Chevrolet Silverado for Installing a Brake Controller
  • For your 2011 Chevrolet Silverado there is not a direct plug in application under the dash that will connect the brake controller and your vehicle. On that generation of Silverados the wiring that connects to the brake controller is established from the factory and is located under the steering column. You will need to locate this wiring bundle, and hard wire your truck wiring to the plug that connects to the back of your brake controller (part # C51515). I have included a helpful article

  • Curt Venturer Brake Controller Shows Green Bars then Red Dot, then the Trailer Jerks
  • On the Curt Venturer brake controller # C74VV, if the red dot is solid that indicates that the trailer is not connected, or at least the brake controller is sensing a disconnected condition. This seems like what is going on. When the trailer jerks that is the brakes engaging and then it goes out again. The likely culprit is a dirty or corroded trailer connector, brake wiring, or the magnets themselves. Make sure the vehicle and trailer side connectors are clean and corrosion free inside

  • How do Electric Trailer Brakes Work on a Travel Trailer and How Often to Grease Bearings
  • Electric brakes do not use brake fluid. They work by a brake controller sending back voltage to an electro-magnet. When energized the magnet stick to the armature surface of the brake drum. The spinning of the drum pulls out the brake shoes and the pads make contact with the inside of the drum, slowing the trailer. As far as how often to grease the bearings it really depends on how much the trailer is used, how many miles are put on it, the conditions you are driving in, and so on. You

  • Brake Controller Installation on 1999 GMC Pickup

They offered both the C/K series which was a carryover from the 1998 model or the Sierra which was an all-new body style. If you have the C/K series, the vehicle isn't prewired for a brake controller. You'll need to begin with a functional 4 pole trailer connector. You can install # 118315 if you don't already have one.
