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: C51451

Install your Curt electric trailer brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your 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 port is located in the wiring panel underneath the dash, to the left of the steering column, 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.

2015 Chevrolet Silverado

After talking at length (at least 15 minutes) to the rep on the phone, I choose the Curt TriFlex controller for my 2015 Silverado. It happens to be the same unit sold on Chevy's website (but cheaper on etrailor). The sales person was awesome! She wanted to be sure I got the right one, not trying to upsell me on something I didn't need. Just as she promised, it plugged right in under the dash and I even used an existing screw to mount the bracket. A 15minute install!!! I will shop here again.



by: OEM09/24/2017

The screws for the bracket did not fit into the plastic bushings in the bracket. I have got hooked this up to a trailer with brakes, yet, but everything else seems to work, including the adapter for my Silvy1500. Note that this review bears no negativity on etrailer, but he manufacturer of the brake controller. Stop letting China manufacture our goods and get better product reviews. I have had good experiences with etrailer.com, they always ship fast and deliver quality installation guides. Kudos to them!



by: Scott09/18/2022

I’m not sure if this part is good or not because it is part of a trailer brake choice that doesn’t work well. It is possible that this is the problem, but no one seems to be able to tell me what the problem is.



by: Wes05/21/2021

This thing does everything you could ask a trailer brake controller to do. Easy to install, easy to adjust, and performs flawlessly. And it is priced right where it should be.



by: Tom F11/19/2020

This is my first order with etrailer.com . The Curt Custom Wiring Adapter was as advertised and came on time as promised.
I had shopped around at All the big three auto parts places (except "NAD*) only to get the same answers: "You have to splice those things to mak'em work"....cost could be around $50-150 bucks" OR " We can't get the connectors from our company". This was not true.
Glad I found "etrailer.com . Thank You ALL. :)



by: Steven M05/18/2015
2015 Chevrolet Silverado 1500

The controller arrived quicker than expected along with the wiring harness. Installation, with your instruction, was painless and simple.

I choose to use velcro to mount my accessories, and in the pictures you can see this is a simple fast method. Plus, I can always remove it easily if need be.

Great product, great support, great prices.

After waiting for almost 1 month I finely received my order had too return one order that was not mine and had to wait until I got instructions on returning it. I have placed 3 different orders with etrailer but the last one was a mess, I don't known where you get the people that work in shipping but I think that a 4 year old could do a better job also when you have a complaint U wind up talking too four or five different persons and no one knows what you are talking about the only person that was of any help was Kim P thanks young lady



by: Danny08/13/2022

It was a very simple install. Only problem I had was getting my fat fingers in the right position to install the adapter harness into place. Took maybe 3 minutes though. Web site said it wasn't compatible with my truck, so I called. After a short wait Jesse came on. He was extremely patient as I explained my problem and had me fixed up in just a few minutes. The shipment arrived 2 days early wich is rare these days. Very pleased for sure.

Ok, I just found a package from you guys on my porch when I got home. I'd gotten an email today that said it'd been delivered, but I KNEW that was a mistake because I'd just ordered a couple days ago, paid ZERO for standard shipping, so was certain there was no way anything got here already. Get home, it's ALL there!!!!! It's all exactly what I ordered, and I'll be providing reviews of the stuff as I get it installed and used. But as for etrailer? Nothing but awesome!!!!!!!!! Amazing job. Now THAT'S customer service!

E-Trailer had exactly what I needed for my new model year vehicle that I couldn't find elsewhere. The product was accurately described and the installation manuals were available online which helped tremendously in making a purchasing decision. The order was placed on a Sunday and a shipping notification was received on the same day literally minutes after the order was placed. Item was received within 3 days...can't ask for better than that.

I have bookmarked this site for future business...very efficient.

Easy installation for brake controller only Con was there were no instructions provided as to where on the fuse block to plug it in. Had to research website for info. Mirrors fit perfect and allow to see rear of 26 ft trailer for up coming traffic

The connector was part of a kit which included the trailer brake. Everything worked as advertised. Plug and play in my 2015 Silverado.

  • 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. Your generation of GM truck is notorious for this fuse easily blowing and when it does brake controllers will stop working with the brake pedal. An easy way to check this is to see if the third brake light on your truck cab still lights up with the brake pedal.

  • Should I Add Electric Brakes To My Trailer
  • Trailer brakes are normally not required if the trailer does not exceed 40% of the towing vehicle weight, however the laws vary by state so it is a good idea to find out your state's laws on trailer towing. I have attached a link that shows you all of the parts needed to add electric brakes to a trailer. You may also want to check your vehicle's owner's manual because some manufacturers require the trailer to have brakes if you tow it.

  • Troubleshooting Curt Venturer Brake Controller Causing Brakes to Lock Up
  • There are a number of issues that could be causing the Curt Venturer # C74VV brake controller to lock up your trailer's brakes so you will need to take a number of troubleshooting steps. To test the brake controller, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester such as # 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

  • What Does Single Red and Single Green Light on Curt Venturer Brake Controller Indicate
  • A single red light on a Curt Venturer Trailer Brake Controller # C74VV indicates that a trailer is disconnected and is more or less a fault code to let you know that the trailer connection was lost. A single green means the controller is active and ready but a trailer isn't connected. Now controllers can act funny when it comes to when they "wake up" but what really matters is how they act when a trailer is connected. Have you tried towing a trailer yet and does it seem to work fine?
