Curt Discovery NEXT Trailer Brake Controller - 1 to 4 Axles - Time Delayed
part number: C84VV

An easy-to-read digital number display, 10 power levels, and a pinch-trigger manual override make this time-delayed brake controller easy to use. Installation is 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 0.5 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 the 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 4 axles (8 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" tall
  • 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 0.5. 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 upper orange 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 10 seconds as a series of bars and then go into sleep mode.


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 upper black 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 Discovery 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 Discovery 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.


Curt Discovery 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 Discovery 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 Discovery. 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: C51322

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. For most applications, this harness is located beneath the dash, near the center console.


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.

They are the best at what they do. They found the parts I needed and got them to me the next day. I appreciate the dedication to their customers. This product worked for my 1997 Ford F350 with the factory-installed tow package.

PERFECT. The etrailer.com employee (Roger R) that assisted me on my phone in order was fast, and efficient. He looked up my truck (2004 f250 diesel 4x4), and assisted me in ordering the exactly correct harness for my application. Plug and play. Thanks.

Excellent. Perfect fit, exactly what was needed. Connected the Curt C51110 Brake control to factory wiring. Only thing that could make it better is if it came with someone to plug it in for me and save me 10 seconds.

The products worked great up until about a few weeks ago Thats when I sold the truck where the items were installed. lol. Really though, I very much liked how the products listed and purchased from etrailer.com were easy to find, fit exactly as described, and performed as needed. etrailer.com is always one of the first places I look when searching for items for my new truck.

Wonderful product as well as wonderful customer service



by: Joe04/13/2021

We purchased our new Ford Explorer with the towing package but the dealership said it didn't come with a trailer brake controller and nothing was made for our SUV so we would have to get an aftermarket controller and have them run the wiring. After looking online I found a video on etrailer.com and it was just as easy as the video to install, the hardest part was finding the Ford plug under the dash, very happy with this product and ready to haul our RV everywhere.

2017 Land Rover Evoque

Made installation in a Land Rover Discovery Sport a breeze! Note: This option isn’t listed on either Curt or eTrailer, but it is absolutely an option if you have the factory installed OEM trailer tow package. Your factory tow package must be dealer activated in your vehicle’s software to use the quick connect harness shown here.

Total plug and play. Zero cutting, splicing or tapping required! Fantastic.

TIP: Select your model year and Land Rover Evoque (Shares the same chassis and tow electrics as the Discovery Sport) if you want the right part numbers for your quick connect options.

2004 Ford F-150

This is well worth the money. The cord ends appear to be high quality and fit the wiring connectors on the truck and brake controller perfectly. It makes hooking up your new Curt brake controller as easy as plugging in a cord. The only way to make this any easier is to have someone do it for you. The hardest part of the whole installation was finding the factory connector to plug this cord into. Hint: On my 2004 Ford F150, the brake controller connector was just above the factory diagnostic port underneath the dash.

2010 Ford Expedition

This cable made the job very easy. took 10 minutes to plug in and mount with Curt Venturer Brake Controller. Very inexpensive solution. This is an old vehicle (2001 Expedition) and didn't want to put a lot of money into a brake controller setup. These parts and directions from the website made it quick, easy and inexpensive. I have not towed with the controller yet.

In a lot of cases the wire colors don't always match up perfectly as sometimes the manufacturers will change wire colors or they use all-together non-standard colors but we know the harness mentioned is the correct one for your Frontier. Since you have a horse trailer and the brakes are locking up I suspect the issue is related to the trailer connectors.

  • Help! Curt Discovery Trailer Brake Controller # C84VV Only Shows Decimal When Brake is Applied
  • Since the Curt Discovery Trailer Brake Controller, # C84VV, is still displaying the decimal when the trailer is connected, the controller is not sensing a connection with the trailer brakes. In this case the issue is most likely related to a wiring problem or brake magnet problem. I would start by making sure that there isn't any corrosion in either connector. Next, I recommend using a circuit tester like part # PTW2993, to make sure that you have power on the brake controller output pin

  • Troubleshooting Brake Controller Install Where Brakes Lock Up As Soon as Brake Pedal is Touched
  • Since your controller is not showing a connection and your brakes are locking up anytime the brake pedal is touched that means that instead of having the brake output circuit connected to the trailer brakes (blue wire of controller) you have a stop/turn signal circuit connected to the circuit instead. You can test this pretty easily by turning on either blinker and you should feel the trailer brakes lock up with the blinker getting activated. Since your brake controller would have been

  • Troubleshooting Trailer Brakes that Lock Up When Trailer Is Connected
  • There is a short or a mis-wire on the 7-way you installed. It sounds like the 12 volt accessory circuit is shorting out to the brake output circuit which is causing the brakes of the trailer to lock up anytime the 7-way is connected. This is a fairly common issue as wiring up connectors is a bit confusing. Since the controller never senses a connection it sounds like the problem is the circuits just being wired backwards. I attached a chart that has what the 7-way pin out should look like.

  • Troubleshooting a Curt Discovery Brake Controller That Has Jerky Brakes
  • Wes, it could be possible that your brakes are jerky after they are warm because you adjusted them while they were cold. So what you can do recommended to warm the brakes by applying the manual lever for a bit while driving at slow speed; once they're warmed you can adjust them properly. Another possibility is that the delay is set too long on the controller. I'd suggest trying to set the delay to activate sooner and see if that fixes it. If all that does not work, then there could

  • Troubleshooting Brake Controller that Only Works with Manual Override Lever
  • This is a fairly common problem and the solution is the red wire of the brake controller. Make sure it is connected to a circuit that only sees voltage when the brakes are applied and none when released. Most likely the connection is the issue and just reconnecting the circuit will cause the controller to work again. You can also check to make sure that the third brake light fuse is in good condition under the hood of the vehicle as well.

However, the Discovery is a time delayed brake controller, which means that it applied the brakes with the same intensity and with a slight delay in response to the tow vehicle's brakes being pressed.
