Features to know about

Fits Tight Spaces with Low-Profile Mount: Installs Anywhere Under the Dash

The main unit is just 1" thick and mounts flush with the dash using the included bracket. There are no angle restrictions, so you can install it wherever it’s easiest to reach. The pigtail harness wires into your vehicle and creates a simple plug connection for the controller. Once mounted, the setup stays clear of your knees and keeps your cab uncluttered.

Keeps Braking Predictable and Customizable: Time-Delayed Power Control

The time-delayed system gives you full control over how your trailer brakes respond. You set the gain for maximum braking power and use the load control to dial in how quickly that power ramps up. It’s easy to match your trailer weight, road surface, or driving conditions. The setup works with trailers that have up to 3 axles (6 brake assemblies) and handles both electric and electric-over-hydraulic systems.

Easy to Read at a Glance: LED Display with Bar Indicators

The LED screen shows clear bar indicators for each setting so you can check your brake output without distraction. It also displays error messages for quick troubleshooting and adjusts brightness automatically or in night mode to cut glare after dark. Everything stays simple and visible from the driver’s seat.

Built-In Safeguards for Reliable Use: Self-Diagnostics and Auto Sleep Mode

Self-diagnostics constantly monitor your trailer connection and check for shorts, while auto-sleep prevents battery drain when not in use. The large manual override sits within easy reach, giving you instant control if you need to stop fast or test your setup before a trip.

Specs

Application

  • 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

  • Dimensions: 4" long x 3-1/8" wide x 1" thick

Warranty

  • Limited lifetime warranty

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
  • If you don't already have a 7-way plug at the back of your vehicle: take a look at the 7- and 4-way brake control installation kit (ETBC7 - sold separately).

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.

  • Will the Light on the Curt Venturer NEXT Trailer Brake Controller Drain My Battery?
    Yes, you can! The display light on the Curt Venturer NEXT Trailer Brake Controller item # C74VV is an LED so it draws an extremely low amount of power from your truck's battery. It will not kill your battery.

  • Troubleshooting Red Flashing Light on the Curt Venturer Trailer Brake Controller # C74VV
    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...

  • 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....

  • Is Curt Venturer Trailer Brake Controller a Plug-and-Play Option on 2014 GMC Sierra?
    If you have the factory tow package on your 2014 GMC Sierra 1500, which from your description it sounds like you do, then the Curt Venturer Trailer Brake Controller # C74VV is plug-and-play. All you need is the Curt Custom Wiring Adapter # C51451; one end plugs into the brake controller and the other end plugs into the port beneath your dash.

  • Curt Brake Controller Wiring Harness for 2018 Toyota 4Runner
    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. Proportional brake controllers use accelerometers so the braking force on the trailer matches your vehicle....

  • Curt Venturer Brake Controller Troubleshooting on 2009 Saturn Outlook
    It sounds like you might have an issue with your ground, or you may need to simply reset your brake controller now that it has been installed. Once you turn your vehicle on and the trailer isn't connected, there should be a red light that appears on the controller. To reset your brake controller, unplug the pigtail harness for about five minutes. After that, plug the harness back into the brake controller. If resetting the controller doesn't work, try grounding the controller to a different...

  • 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...

    I can help you figure out what's going on with your Curt Venture # C74VV. First lets start with the Red Light that comes on intermittently. 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. If your red light is flashing instead of solidly lit, according to the directions, a flashing red light indicates that...

  • 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. Let me know what you find when you do this and we can see what's best route to go.

    If you are reading a constant 12 volts on the blue brake output wire with the Curt Venturer Brake Controller # C74VV installed, this is indeed an indication that either the controller itself is bad or there's a short somewhere along the brake output wire on your truck (between the controller and 7-Way connector).
