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

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: C51352

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 junction box 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 electric junction box 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.


Junction Box on VehicleBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


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.

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.

Slimmer than most of the others. Easy install with the additional pigtail.



by: Pete D.07/28/2016

The Curt electric brake controller was the easiest installation I have ever had. I ordered the custom wiring adapter along with the brake controller; it all came with easy to follow instructions and it only took about 30 minutes to install the entire unit. I had done some checking around to get estimates from various companies which do the installations and their costs were around $300.00. The Curt unit including the adapter wiring was $**.00 and a very easy install. I used the brake controller during a recent camping trip on which I was pulling a 24 foot camp trailer. The controller worked great and I could easily control the trailer in some extreme mountainous terrains in Wyoming.

The adapter is as advertised, although I have an older brake controller that I had to do a small amount of wire splicing.

Bought this trailer controller cable with a Curt Trailer Brake Controller. I dont know if it works or not. I installed this along with thr trailer brake controller at the same time. Nothing works. No lights power up on the controller. I highly respect Curt Products as I have many installed on my truck, but I'm disappointed with this combo purchase.

by: Jim S.04/21/2014

Given the fact that I only planned to tow my travel trailer one way up to the lake, I wanted an inexpensive brake controller. I looked online and in stores, and they were all over $100. When you added in the wiring. The controller I purchased from E-trailer only cost $49.99 including the wiring. I simply plugged it in, and after a short test tow, it works great. Took about 15 minutes to install. I'm very satisfied with my Curt brake controller. Got it in 3 days after ordering. Arrived fast, installed fast, and works great at a great price. What more can you ask? I'll be ordering from E-trailer in the future. Thank you.

Appears to be the correct harness as the plugs match the brake unit and the splice in GM pig tail that came with the truck. Bought it to avoid cutting and splicing as well as avoiding voiding the brake unit warranty. Big Benefit also that I can unplug and move to another vehicle if needed Had the unit within 5 days including the week end, that's great customer service by etrailer

Im still using the above items and have had no problems with them. Thanks.



by: none11/16/2014

Great price and prompt order processing. Controller mounting kit and harness made for a very easy install; about 20 minutes. Unit worked without any problems on a recent 300 mile trip with a horse trailer. Went over some fairly steep inclines in the Blue Ridge area of Virginia. Chose Curt Tri-flex controller over the more expensive brands because two of the three trailer dealers in the area carried those units as their default controller. The unit has all the braking functions without the fancy screens and interfaces. Found that I rarely looked at the controller display and the discrete black box worked for me.



by: Don Douglass 11/14/2016

Second time I have ordered parts for towing my trailer. Product was a snap well 2 snaps to install and works perfectly. Allows me to move my brake controller between both my vehicles. Used customer service this time as well and was extremely satisfied. Staff was knowledgeable, kind, and friendly.



by: Perry11/28/2017

First, let me say that I have never been disappointed with any of my transactions with etrailer. This holds true with my latest purchase of a Curtis brake controller and pigtail. This is my second because the first was fried when the trailer wiring shorted out. I received the controller in 3 days, which included a partial weekend. The pigtail make installation so simple. I literally had the old controller out and the new one in within 5 minutes. I will look at etrailer first for any of my trailering needs.

This made installation of the brake controller a dream. Connect to controller and plug into the port for the truck, 2005 Chevy 1500 Silverado. No muss, no fuss. Total installation time was about 20 minutes.

-Plug in and go--- Quick and easy installation. Works great. etrailer was great to deal with. I had a missing part in one of the boxes, due to careless shipping, and I E-mailed about the part and etrailer sent a new part right away. Thanks for great service.

Great way to get an electric brake controller wired into your vehicle. GM was real smart to put a plug receptacle in the electric box for the electric brakes for trailers. etrailer shipped my order right away and all the items ordered were in great shape. Will be buying from them again.

  • 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.

  • 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

  • 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)

I have linked you to an FAQ article that describes how to install a brake controller on a 2003 GMC Sierra.

  • You will likely have to make at least one connection under the hood of your 2007 GMC Sierra Classic to power the brake controller. You may also need a fuse. I have included a link to the right that shows the connections that you will need to make under the hood to make everything fully functional.
