Features to know about

Fits Cleanly Under the Dash: Compact 1"-Thick Controller

Bulky brake controllers can clutter your cab space, but this one keeps things simple. At only 1" thick, the CURT Venturer NEXT mounts flush with the dash using the included bracket and hardware. You can place it anywhere at any angle without restrictions, so it stays out of the way while staying easy to reach when you need it.

Keeps Braking Simple and Reliable: Time-Delayed Control for Up to 3 Axles

When you hit the brakes, the Venturer NEXT sends power to the trailer brakes at a preset intensity and rate. You control both gain and load with rocker switches—gain sets maximum brake force, and load fine-tunes how quickly that force builds. It’s compatible with trailers up to 3 axles (6 brake assemblies) and works with electric or electric-over-hydraulic systems, plus low-volt, PWM, ABS, and cruise control setups.

Shows You What’s Happening: Bright LED Bar Display

You don’t have to guess what your brake controller is doing. The LED display uses bar indicators so you can see your settings at a glance. It shows error codes for quick troubleshooting and even adjusts its brightness or switches to night mode so it won’t glare on dark drives.

Gives You Fast Access When You Need It: Large Manual Override

In sudden stops or sway situations, you can apply trailer brakes instantly without touching your vehicle’s pedal. The large pinch-trigger override is easy to grab while keeping your eyes on the road. That direct control gives you extra confidence when towing heavy loads.

Installs in Minutes: Plug-In Harness Connection

No cutting or splicing required—the custom harness plugs directly into your vehicle’s factory brake control port under the dash. Once connected, simply plug in the Venturer NEXT. The design makes installation quick and clean, with auto-sleep mode built in to prevent battery drain when not in use.

What is Time-Delayed Braking?





Time-delayed braking means that when you apply the brakes in your vehicle, the controller activates the trailer brakes at a pre-set intensity and rate. 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.

Video Transcript for Curt Venturer NEXT Trailer Brake Controller w/ Custom Harness Feature Review

Hi there. I'm Michael with etrailer.com. Today we're gonna take a quick look at this CURT Venturer NEXT Trailer Brake Controller. Now, if you're not familiar, if you have electric trailer brakes on your trailer, you are going to need a brake controller in order to activate those brakes. Otherwise, they're not really doing anything for you. There are several different kinds of brake controllers out there, different features and that sorta thing.

This is really gonna be your more basic option. So it's not gonna have some of the more advanced features that allow you to control the intensity of your braking in the moment, but this is going to be enough to get your brakes functioning. So if you are just looking for the base model that's gonna do the job for you without having to pay a whole lotta money, this is gonna be a great way to go. This will work for your trailers that have up to three axles, so six brake assemblies. Basically the way this works, every time you apply the brakes in your vehicle, a signal is sent via your brake switch to the Venturer.

The controller is then gonna send that power out to your trailer brakes to activate them with an intensity that's preset by you. It does also have the predetermined rate, which is also set by you, and we'll get into what those two terms mean, but this is going to be a time delay system. So unlike some other brake controllers that are proportional, this is going to apply the brakes at the same intensity whether you're tapping on the brakes or slamming on the brakes in an emergency sorta situation, that your trailer's brakes are gonna apply at the same rate either way. Both the amount of your braking power, called the gain, and the rate of the application, which is called the load, can be adjusted to suit your preferences, the road conditions, the type of trailer you have, and the weight of your load. We've got the switches here that are going to allow you to very easily access that and adjust.

So we've got 10 different gain settings. You select a higher setting for your harder braking and a lower setting for your more gradual braking. You do wanna go as high as you can without your trailer's brakes locking up. That's a good indicator that you've gone a little too far, so you wanna come back down a little bit. Typically your gain is only gonna be readjusted when you're experiencing changing road conditions or if the weight of your trailer changes.

So if you've taken off your load, you might wanna adjust it so that it's not engaging as hard with that lighter empty trailer. This also provides nine different load settings, and that's gonna control the aggressiveness of your trailer's braking, meaning how quickly the brakes reach their maximum braking level. So you've got all that adjustability to preset it, but then once you apply the brakes, it's going to apply that same power and as quickly each time. So again, whether you're tapping on the brakes or you're slamming on them, the trailer's brakes are gonna apply that same amount of pressure. So unlike your proportional systems which will apply the trailer's brakes in proportion to how intense you're applying the tow vehicle's brakes, this is not gonna have that feature. It does have a very simple LED display that's gonna show the amount of power output. So you can adjust that in one-digit increments so that you can know where you're at, you know how much intensity you've got. The brightness is also adjustable, so you can view it optimally either. No matter if you're driving during the day or at night, you can adjust that brightness level. We also have the pinch trigger that's going to give you that manual override capability, so very easy to reach if your trailer begins to sway or if you're stopping in an emergency situation. You can activate your trailer's brakes and the brake lights without having to apply the brakes on your tow vehicle just by pushing in on that switch or that trigger there. This is gonna be very quick and easy to get installed. There really are no mounting restrictions. So with a proportional system, you have to have it mounted in a certain orientation for the internal components to sense the inertia. This, you don't have to worry about that. They've got this mounting bracket here with the included hardware that you can get mounted flat on your dash, and then it just kinda slips in place there, so basically flush with your dash. Very simple to get installed, and you don't have to worry about getting a certain orientation. You can mount it basically whichever way is gonna work best for your setup. You can see our width there. We're looking at approximately 3 1/8 of an inch wide. Our length, we're sitting at approximately four inches, and then our thickness, call it about an inch. So keep that in mind when determining where you're gonna mount this. Now, to get it wired in, it's gonna depend on your setup. If your vehicle is already equipped with a plug-in brake controller wiring harness, all you have to do is just connect the unit to it, so very simple there. If you don't have a built-in system, there are some plug-in vehicle-specific brake control wiring adapters available that are gonna help to reduce your installation time, and of course, that is gonna depend on your vehicle. So I'd recommend using our vehicle fit guide here at etrailer.com. You'll select your year, make and model of your vehicle. We'll let you know which products will work for you. So specifically for those vehicle-specific kinda products, that's more important, but if you do have one of those available, I'd highly recommend going with that. Otherwise, if you are just going to wire it in place, you are gonna need either the 20-amp circuit breaker if you have a two, three or four-brake application, so with two or four-brake application, or you'll need the 30-amp for a six-brake application. So depending on your setup, you'll need either one of those, and again, if you don't already have a seven-way plug at the back of your vehicle, I highly recommend our ETBC7 seven and four-way brake controller installation kit that you can see on the screen there. So that's gonna give you that plug at the back of your vehicle so that you can plug in your trailer's wiring and make sure everything is connected properly. This does come with a limited lifetime warranty. So if you we're to have any issues with it, you're more than welcome to reach out to us here at etrailer.com, but like I said, this is a very basic model. I think it's gonna get the job done for you. It's not gonna have a whole lot of bells and whistles and that sort of thing, but it is gonna help to apply those brakes on your trailer, and that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

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.

    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.

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...

  • Green Light On all the Time for Curt Venturer Brake Controller
    A single green light with the Curt brake controller part # C74VV means that no trailer is connector and the manual override or brake pedal is pressed. If you are seeing that all the time you most likely have a short between the power wire of the controller (black) and the stoplight wire (red) which makes the controller think the pedal is applied. Use a circuit tester like part # PTW2993 to probe the red wire of the controller. If it's seeing voltage all the time then my theory is correct....

    Hey Jody! If you have factory wiring with a tow port under the dash the Curt Venturer NEXT # C57SV is the better choice. This includes a custom wiring harness for a plug and play installation. It is worth mentioning that this is a time delayed controller, which really isn't the best for towing. I recommend getting a proportional brake controller like the TriFlex NEXT # C67GV instead.

To reset your brake controller, unplug the pigtail harness for about five minutes. After that, plug the harness back into the brake controller.

  • 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...

  • Why Would Using 7-Way to 5-Way Adapter Not Let Boat Trailer Reverse
    Hey John, the issue is that your reverse lockout solenoid is not activating on your trailer using the 7-way to 5-way adapter you have. This is most likely due to your 2023 Nissan Frontier 7-way not having the reverse light circuit active as this circuit is active on every vehicle. You can test this with a circuit tester like the # PTW2992 to test the center pin of your 7-way when the vehicle is reverse.

  • Comparing Redarc Liberty and Curt Spectrum Brake Controllers For a 2023 GMC Sierra 1500
    Personally, I have seen a lot fewer issues with the Redarc Tow-Pro Liberty # RED24FR than with the Curt Spectrum # C51170. The Spectrum was released in early 2018. Currently Redarc only offers the one size control knob. To install the Redarc Liberty # RED24FR in your 2023 GMC Sierra 1500 you will need the Tekonsha Pigtail # 3064-P and the Redarc to Tekonsha Adapter # 331-TPH-017.

  • Brake Controller For Towing Trailer With Electric Over Hydraulic Brakes 2021 Chevy Silverado 2500

  • Where Is Factory Trailer Brake Controller Port On 2021 Chevrolet Tahoe W/ Factory Tow Package?
    The factory trailer brake controller port on your 2021 Chevrolet Tahoe is located underneath the dash just to the left of the steering wheel.

Keep in mind that if your Tahoe does not have the factory tow package, the connector may not be there and you would need to hardwire a controller.

    If that part is available it would be through GM only. But you could also bypass needing a connector and just wire what you have found directly to a brake controller like the Brake EVN part # TK63VR instead.
