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'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.

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.


Delivered early. Was just what I wanted.


Almost plug-n-go.The hardest part was where to put the controller !

  • Location of Trailer Brake Controller Connection Port on 2015 Toyota Tundra
    Current model Toyota Tundra trucks equipped with the factory 7-way trailer connector have their brake controller connector located behind the panel to the right of the ignition key that contains the Tow/Haul button, as you can see in the photo I've provided for you. You'll need # 3031-P brake controller wiring harness to connect a Tekonsha controller such as their P2 # 90885. If you are using a Curt controller like the Venturer # C74VV then instead you'll use harness # C51455.

  • How to Add a 4 and 7-Way Trailer Connector to a 2011 Ford Ranger
    The best option I have for you to add a 4-way trailer connector to your 2011 Ford Ranger is with the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 56014. The reason that this is the best option is because it does not require any cutting/splicing, it will just plug in behind each of your taillights. If the trailer you will be towing with your Ranger has brakes then you will also need both a 7-way trailer connector and a brake controller. For a 7-way,...

  • Trailer Brakes Will Not Work and 2006 Chevy Silverado Lights Malfunction w/Curt Brake Controller
    It sounds like the red wire in the wiring harness # C51352 was not in the correct place. Take a look at the picture I have included and make sure that the wires in your harness are in the same places. This is the end that plugs into the truck. It needs to plug in at the junction box under the dash, to the left. It will plug into the spot that is on the top row, second from the left. The wire functions are white for ground, black for 12 volt power, blue for output to trailer brakes, and...

  • What is Causing My Curt Venturer to Flicker on the Controller?
    I'm so sorry to hear about your brake controller! I went ahead and brought the issue to my tech at Curt, and he confirmed that it is possible that there is an opening in the wiring or housing that is causing the signal to flicker on your Curt Venturer # C74VV. This is probably the case if you noticed that this only occurs in wet conditions. One way to confirm this is to see if this occurs during dry conditions (or occurs again in wet conditions). The only other possibilities are a short...

  • 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....

  • Parts Needed to Install a Brake Controller on a 1996 Chevy S-10
    The plug under the dash you see is likely the OBDII port and you are correct, it is not used to install a brake controller. On your 1996 Chevy S-10 you will need to hardwire in a brake controller. To do this you will need to start by installing a trailer connector (unless the truck already has one). To start you would install a 4-Way, # HM41115. If the truck already has a 4-Way you can skip this step. Next you will need 4 and 7-Way installation kit # ETBC7. This provides the 7-Way and...

  • Trailer Brakes Dont Engage Completely and Brake Controller Not Showing Full Power
    It sounds like there might still be some wiring issues in addition to the one that you found, but I think your best bet to start with this issue is by pulling the pin on the breakaway system on the trailer; this will allow us to figure out if these issues are being caused by the brakes/wiring or if the problem lies somewhere else. If you pull the pin and the brakes don't lock up completely, the issue is going to be on the brakes and/or brake wiring; if the brakes lock up completely, we...

  • Trailer Brake Lights Not Working After Brake Controller Install
    The first thing you will want to do is test the 7-way connector at the rear of the vehicle using a circuit tester like part # PTW2993. If the brake signal is reaching the connector, you have a bad ground and you will need to ensure the ground wire is attached to a bare metal surface free of corrosion. If the signal is not reaching the back of the connector, may have attached the stop light switch (red wire) from the Curt Venturer Trailer Brake Controller part # C74VV to the wrong circuit. The...
