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: C51312

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 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 harness is located underneath the dash, to the left of the steering column, and it is taped to another harness 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.

  • Troubleshooting Curt Venture Brake Controller that Wont Release Brakes Till Tapped
  • Curt brake controllers like the Venturer part # C74VV that you have are known to have odd issues like you mentioned which is frustrating. What you can do is try unplugging the brake controller for a few seconds and then plugging it back in to see if a reset fixes the issue. Best solution is going with a more reliable controller like the P3 part # 90195 as this is basically the most reliable brake controller out there.

  • 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.

  • Red Light on Brake Controller Sometimes Comes on When Using High Beams with No Trailer Connected
  • You have a unique situation that I've never ran across before. So I reached out to my contact at Curt and he's thinking that the ground wire on your Curt Venturer Brake Controller # C74VV has power coming through it from the high beam switch of your truck. To test this he said to cut the ground wire and test the current through it. If it reads inconsistent then this is your problem. He suggested using a diode (part # RM-790) on the ground wire, or replace the high beam switch in

  • How to Install a Curt Brake Controller in a 2014 GMC Sierra
  • Yes, you can. If your 2014 GMC Sierra is a 1500 model all you would need is the Curt Wiring Adapter part # C51451 to install your Curt Venturer Trailer Brake Controller # C74VV. If your 2014 is a 2500 or 3500 the connections are available under the dash of your vehicle. You would want to wire the controller up to the wires under your dash. Check out the FAQ article I attached on how this is done.

  • Does a Trailer Need a Battery for the Brakes to Work
  • No, you do not need to have an auxiliary battery on the trailer in order for the brakes to work. The brakes are powered by a brake controller like part # C74VV which draws power from the tow vehicle's battery, not the trailer's battery. You will however need a battery on the trailer to activate the breakaway which is required by law in most states however, this battery is very small and is included with most kits like the Curt Push-To-Test Trailer Breakaway Kit part # C52044.

  • Blue Wire on Curt Venturer Brake Controller has Voltage with Just Power and Ground Wires Connected
  • If the blue wire on the Curt Venturer Trailer Brake Controller # C74VV is putting out 12 volts then that would indicate there is a short inside the controller and it will need to be replaced. If you have a meter such as # PT89ZR use it to check for amperage as well on that blue wire. If there is no amperage then it is dead voltage (which is weird but normal for Curt brake controllers). Also be sure that you are using the black wire for power into the controller and the white for ground.

  • Recommended Brake Controller for 2017 Land Rover Discovery
  • Your 2017 Land Rover Discovery can have a brake controller added, but there is not a custom wiring harness. This simply means you will hardwire a brake controller like # C74VV you asked about. I am not a fan of this particular controller you have asked about, so I recommend you go with a proportional controller like the Prodigy P3 # 90195 or a more cost efficient option like # TK90160. The difference is the proportional controllers have an integrated sensor so they determine deceleration

  • Where to Mount a Trailer Brake Controller on a 2014 Nissan Pathfinder
  • As long as the brake controller you are using is mounted within the parameters specified in the instructions and within easy reach of the driver you can mount it anywhere that is convenient for you. To secure the wiring to the brake controller you can use wire ties to hold it to another harness or a part of the dash so the wiring does not get in the way of your feet or pedals. I would try to mount the controller on the right hand side of the steering column if there is space. Most of

  • Using Quick Connect Wiring Harness On 2008 Ford Explorer Sport Trac With Factory Tow Package
  • The custom wiring adapter you can use for your Explorer is the Curt Custom Wiring Adapter, part # C51322. This will easily plug into the vehicle wiring harness under the dash near the center console. There will be a 6-pin connector that mates with the one on the adapter at the end of the harness. Verify that there is battery power supplied to the connector by carefully probing the connector with a circuit test light like part # PTW2993. If you have a 7-way connector at the rear of your

  • 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)

  • Troubleshooting Curt Venturer Brake Controller with Flashing Red Light on Display
  • I checked with Curt and the flashing red light indicates a brake circuit overload, or a solid red light means that no trailer is detected. If the light is flashing that most likely means you have a short somewhere on the brake output circuit, but since there isn't a trailer connected most likely you have a dirty trailer connector at the rear of your vehicle that has a bit of corrosion that is causing a slight amperage draw which is confusing the brake controller. Try cleaning the pins

  • Curt Venturer Brake Controller Shows Green Bars then Red Dot, then the Trailer Jerks
  • On the Curt Venturer brake controller # C74VV, if the red dot is solid that indicates that the trailer is not connected, or at least the brake controller is sensing a disconnected condition. This seems like what is going on. When the trailer jerks that is the brakes engaging and then it goes out again. The likely culprit is a dirty or corroded trailer connector, brake wiring, or the magnets themselves. Make sure the vehicle and trailer side connectors are clean and corrosion free inside

  • How do Electric Trailer Brakes Work on a Travel Trailer and How Often to Grease Bearings
  • Electric brakes do not use brake fluid. They work by a brake controller sending back voltage to an electro-magnet. When energized the magnet stick to the armature surface of the brake drum. The spinning of the drum pulls out the brake shoes and the pads make contact with the inside of the drum, slowing the trailer. As far as how often to grease the bearings it really depends on how much the trailer is used, how many miles are put on it, the conditions you are driving in, and so on. You
