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.

  • Mounting Curt Venturer NEXT Trailer Brake Controller
  • Curt has started using new brackets for their brake controllers, and that is also true for the Curt Venturer NEXT Trailer Brake Controller # C74VV. To mount this, all you have to do is put the included adhesive tape onto the included bracket and stick it wherever you like under your dash. If you'd like, you can also use the included screws with the adhesive to mount the bracket under your dash. With the bracket mounted, you'll just slide the Venturer NEXT controller into the bracket

  • Will Trailer Brakes Lock Up When Output On Brake Controller Is Set To Maximum
  • When you adjust your output to maximum on the Curt Venturer, part # C74VV the brakes will be applied aggressively but will not lock them up as you questioned. It is a time-delayed brake controller and will apply the brakes to aid in braking as you need. If you move the manual adjustment to maximum you will apply the brakes even more aggressively.

  • Location Of Under Dash Brake Controller Port On 2002 Ford F150
  • You are right that the gray port is right next to the diagnostic port under the dash on your 2002 Ford F-150 for the brake controller. I have attached a photo that shows where the brake controller port is in relation to the location of the diagnostic port. I have also attached a helpful article for brake controller installation on Ford full-size pickups you can check out.

  • Brake Controller Recommendation for a 2006 Nissan Titan for Tent Trailer
  • The Curt Venturer part # C74VV would have plenty of braking power to activate the brakes on the tent trailer you are purchasing. This controller can activate up to 3 brake axles so it would be more than powerful enough. I do have a better option for you though. The controller you referenced is a time-delayed controller. Which means that it applies a preset amount of braking power at a preset speed every time you touch the brakes. That can work out decently, but in reality rarely do people

  • Do Brake Controllers have Constant Power or Do they Wire Into a Ignition/Accessory Power Source
  • Brake controllers such as # C74VV 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

  • How to Install a Curt Brake Controller in a 2014 GMC Sierra
  • Yes, you can. If your 2014 GMC Sierra is a 1500 model all you would need is the Curt Wiring Adapter part # C51451 to install your Curt Venturer Trailer Brake Controller # C74VV. If your 2014 is a 2500 or 3500 the connections are available under the dash of your vehicle. You would want to wire the controller up to the wires under your dash. Check out the FAQ article I attached on how this is done.

  • Curt Trailer Brake Controller Does Not Apply Trailer Brakes when Connected to 2005 Honda Odyssey
  • The most likely culprit is going to be either a dirty or corroded trailer connector or brake magnet wiring. This can cause a short or a weak connection. First, disconnect the trailer and examine the vehicle side connector. Clean off any dirt or corrosion on the pins. Also check the back of the connector where the wires attach because corrosion can build up there as well. Once you have done that use a circuit tester like # PTW2979 if needed to test the brake output pin (5:00 position)

  • Parts Needed to Install a Curt Trailer Brake Controller on a 2003 Chevy Blazer
  • Brake controllers are not vehicle specific so you can use the Curt Venturer on your 2003 Chevy Blazer. There are a few things that you will need first though. If your Blazer does not already have a 4-Way trailer connector then you will need to add one using # 18252. Then after the 4-Way is installed (or if the Blazer already has a 4-Way) you will need to install a 4- and 7-Way installation kit # ETBC7. The 4-Way plugs into the matching 4-Way on the ETBC7 and the remaining wires will

  • Trailer Brakes Locking Up Even After Adjusting the Settings Per Instructions
  • First, you will want to figure out where the problem is occurring. Test the voltage from the brake controller at the vehicle end trailer connector. What you have your brake controller set at is what the voltage should read at the connector. If you are getting more voltage at the connector than what the brake controller set at, you will want to move your troubleshooting to the brake controller. If the voltage is reading correctly at the vehicle end trailer connector, then the problem is

  • How To Install A Brake Controller On 2019 Chevy Equinox With Factory Package

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.

  • Determining Electric Trailer Brake Connection to Travel Trailer
  • When you connect your 2009 Keystone Passport to your towing vehicle, if you have a brake controller connected to your 7-way, then there will be a slight draw on the brake output wire letting the controller know the trailer is connected. Depending on your controller, there will be some indication that the trailer is connected. The slight draw on the brake output wire will activate the brake controller so it will function within your determined settings. To test the connection, I recommend

  • It could be a short on the blue wire which is the brake output wire. When you replace the magnets make sure that they are grounded to a clean and corrosion free bare metal surface near the magnets. Also make sure none of the wiring to the magnets is pinched or frayed and fix as needed. Check the trailer and vehicle side connectors to make sure they are free of corrosion inside and out (including where the wires attach at the back).

  • If you check out the picture that I attached you can see that your Curt Venturer Trailer Brake Controller # C74VV that you installed is detecting an overload or short on the brake circuit of your 2008 GMC Sierra. The wiring adapter # C51515 that you also installed is the correct adapter so now we need to determine if the problem is on your Sierra or your trailer. If you have another trailer with brakes handy then you can simply hook up to that trailer and see if the same thing happens. Whether

The loss of the trailer, intentional in your case, should result in a solid single red light. If this is more of your issue than blinking, the controller is just functioning the way its supposed to when the trailer isn't hooked up.
