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: C51342

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 junction box 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 electric junction box 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.


Junction Box on VehicleBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


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.

I purchased a Curt brake controller from the Chevy dealership and when it arrived it was a controller and a hand full of wires to splice into my system. I got a hold of etrailers and the staff was pleasant and sold me what I actually wanted from the dealership. Now I know to call these guys for all my trailer wiring needs.

This made installing my Trailer Brake Controller a breeze. I had a harness already that came with my truck, but would have to get the connector and pins to put on it to mate it up to the controller. This was already done and ready to go. 2 minutes time to installt he brake controller and have it ready to go.

  • Red Screen on Curt Venturer Trailer Brake Controller
  • I checked the owner's manual for the Curt Venturer Trailer Brake Controller part # C51110, a flashing red display indicates that there is a brake circuit overload, likely caused by a short. It really didn't give any other detail aside from this so I first recommend you check to ensure the wires are hooked up correctly. The black wire goes directly to the positive battery terminal, there should be around 12 volts on this wire as it goes into the trailer brake controller. The white wire goes

  • Mounting Curt Venturer NEXT Trailer Brake Controller
  • Curt has started using new brackets for their brake controllers, and that is also true for the Curt Venturer NEXT Trailer Brake Controller # C74VV. To mount this, all you have to do is put the included adhesive tape onto the included bracket and stick it wherever you like under your dash. If you'd like, you can also use the included screws with the adhesive to mount the bracket under your dash. With the bracket mounted, you'll just slide the Venturer NEXT controller into the bracket

  • Low Brake Output Power on Truck 7-Way with Brake Controller Installed and Engine Off
  • The dim light on your tester is indicating a small amount of power coming from the brake output pin of your 7-Way. This is completely normal with a trailer brake controller installed like your Curt Venturer # C74VV. Trailer brake controllers will constantly send back small, short pulses of power back to the 7-Way and it's basically the controller's way of checking for a connection with a trailer. The amount of power it uses for this is extremely small so you don't have to worry about

  • 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

  • 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.

  • Brake Controller Wiring Harness for a Curt Brake Controller on a 2012 Dodge Ram
  • I have heard that Dodge dealers will tell customers this exact information. The thing is that all that might be true if installing the Dodge controller. But for an aftermarket controller I have not heard that you have to use a 9 Volt controller or that the computer has to be reprogrammed. We have had plenty of customers with 2012 Rams install aftermarket controllers without any issues. All you need is the proper brake controller wiring harness.

  • Will Trailer Brakes Lock Up When Output On Brake Controller Is Set To Maximum
  • When you adjust your output to maximum on the Curt Venturer, part # C74VV the brakes will be applied aggressively but will not lock them up as you questioned. It is a time-delayed brake controller and will apply the brakes to aid in braking as you need. If you move the manual adjustment to maximum you will apply the brakes even more aggressively.

  • 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.

  • Curt Venturer Red LED Light Only Comes On with No Trailer Connected and Stepping on Brake Pedal
  • On the Curt Venturer brake controller # C74VV the LED light should glow red all the time when no trailer is connected. If the light is flashing red when you step on the brake pedal then the controller is sensing an overload or short circuit. You mentioned that you have not towed the trailer in awhile. What usually happens is corrosion on or inside of the trailer or vehicle side connectors. Make sure the trailer and vehicle side connectors are clean and free of corrosion inside and out. Since

  • 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.

  • The relay you need to activate the 12 volt power circuit of your trailer connector is available at your local Ford dealer. I wish we carried it so that you could get it from us but we do not. The correct harness to install the Curt Venturer Brake Controller part # C74VV in your 2008 Ford F150 would be the part # C51322. This harness will plug into the back of the brake controller and the other end will plug into the port under your dash near the center console.

  • Troubleshooting A Curt Venturer Brake Controller That Is No Longer Working
  • Per the instructions for the Curt Venturer Brake Controller, part # C74VV, a blinking red light means there is a brake overload or a short. The probable solutions listed for this is to confirm the brake maximum load of 6. If that is not the issue, then you will need to locate the short and fix it. If you find no short in the system, the controller may be bad. You will need to test the wires at the back of the brake controller for proper input and output. The red wire should only have

  • Recommended Brake Controller For 2015 Class C RV
  • To be honest I am not a fan of the time-delayed brake controllers. Since you set the braking intensity before driving you may run into a situation where it is applied too aggressively or not aggressive enough. I prefer a proportional brake controller like the P2, part # 90885. The P2, part # 90885 applies the brakes in direct proportion to the intensity of the braking action in the RV.
