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.

Everything was as described. Easy easy installation in 10 minutes. Not the top of the line controller but it's all I need. Very fast shipping as well. Couldn't be more happy with etrailer. I will be purchasing my fifth through etrailer soon!

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.

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.

  • 2014 Cadillac Escalade Wont Start After Curt Brake Controller Installation
  • Thanks so much for the purchase from us of the Curt Discovery Trailer Brake Controller # C84VV for your 2014 Cadillac Escalade, and I'm sorry to hear of this issue you are having. This controller, which you'd use with Wiring Adapter for Curt Trailer Brake Controllers # C51515 assuming the Escalade had a factory 7-way already, should not have anything to do with the vehicle starting or not, which means there was a mistake somewhere along the way with the wiring process.

  • Installing a Brake Controller in a 2009 Chevy Suburban
  • The 2009 Chevy Suburban does not have a port to plug in a brake controller which is the same as the trucks of the same year. But it does have the tow package wire bundle up under the dash, to the left of the steering column, held together with a white tag. Pull the wire bundle out to wire in a brake controller. With Curt brake controller # C84VV you will also need pigtail # C51515. Then you can make the following connections: Vehicle red/black wire to controller black wire for 12

  • Curt Discovery Brake Controller # C84VV Generates Output Signal at All Times
  • Thank you for your recent purchase from etrailer of a Curt Discovery Brake Controller # C84VV and harness # C51515. The blue output wire on your Discovery brake controller should carry an output signal under two conditions: when the brake pedal is pressed or when the manual override slide bar is engaged. Since your unit generates output continuously without either of these conditions met this means that either the unit is malfunctioning or that the red input signal wire to the controller

  • Turn Signals Work But Brake Lights Do Not Light Up
  • You came from a brake controller page when you asked the question. Is this issue related to the installation of the brake controller? Or are we just talking about brake lights on a trailer or vehicle? If it is on the trailer then usually there is a bad ground connection since the brake lights draw more constant power than the turn signals. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached

  • Troubleshooting "Short" Error Code On Curt Discovery NEXT Trailer Brake Controller C84VV
  • Hello Surg. It is definitely odd that you are seeing the "short" error code on the Curt Discovery NEXT Trailer Brake Controller # C84VV, especially since your Tacoma was pre-wired from the factory. Nonetheless, this error code is definitely not normal, and is an indication that something is wrong. The display should show the current gain setting when the manual override is applied. With no trailer connected, the "short" code means that the red wire is connected to ground side of the stoplight

  • Curt Discovery Brake Controller Is Only Showing A Dot When Engaging Manual Override
  • The Curt Discovery Trailer Brake Controller, # C84VV, should show only the decimal point dot when the controller is activated and a trailer is not connected. If it shows the dot all the time, the red wire is connected to the wrong side of the stop light switch or the wrong switch completely like the cruise control. If you have only the decimal point when the trailer is connected, the usual cause is that the brake controller does not sense the trailer brakes. This could be due to corrosion

  • Brake Output on Connector with No Trailer Connected Using Curt Discovery Trailer Brake Controller
  • In regards to the Curt Discovery Trailer Brake Controller part # C84VV, there should not be power on the brake output pin inside the trailer connector without a trailer hooked up. There could be a few different things causing this but in order to rule out the brake controller you'll want to do a bench test outlined below. If the controller test good then that means you have a short on the brake output wire on the vehicle and you'd need to start tracing and checking for shorts. It may also

  • Troubleshooting Brake Controller that Flashes When Connected to Trailer
  • It sounds like the problem is corrosion on the trailer 7-way brake output circuit which is causing the controller to only show an intermittent connection. Try cleaning off this pin on the 7-way with some fine grit sandpaper. Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like part # PTW2993, you should get output to the controller side of

  • Troubleshooting Trailer Brake Controller that Only Functions When Engine Isnt Running
  • That is an interesting problem you are having, but the problem lies somewhere in the wiring of the brake controller/7-way. The only way a brake controller is going to work properly with the key in the ACC position but not when the vehicle is running has to be due to wiring. Check to make sure there are no shorts between the two wires you ran to the rear of the 7-way. It sounds like you ran a wire for the 12 volt accessory circuit and an additional wire for the brake output. You might

  • OL Message on Curt Discovery Trailer Brake Controller
  • There could be a few different things happening with your Curt Discovery Trailer Brake Controller part # C84VV. The first thing that could be happening is that you have a short on the red stop light switch wire. In order to rule this out you will need to probe the red wire going into the back of the brake controller. There should only be power on this wire with the brake pedal depressed. If there is when it is not then you know there is either a short in this wire or the stop light switch

  • Troubleshooting Brake Controller that Doesnt have 12 Volts on Red Wire when Brakes are Applied
  • The red wire of the controller needs to be showing voltage when you apply the vehicle brakes otherwise the controller is never going to activate when you apply the vehicle brakes. You need to verify the circuit you are trying to connect that wire to has 12 volts when the brakes are applied. Issue could also be the connection isn't being made completely and you'd just need to make the connection better.

  • Installing A Brake Controller in a 2008 GMC Yukon XL Without Plug and Play Adapter Harness
  • On your 2008 GMC Yukon XL, there is not a direct plug and play harness for a brake controller.

You will connect the brake controller wiring with the vehicle wiring already present under the dash with butt connectors like # 05731-5.

  • Curt Time Delay Brake Controller Not Working with Brake Pedal on a 2015 Ram 1500
  • First, make sure you are using the proper wiring harness for your 2015 Ram 1500 and Curt brake controller. You should be using # C51438. Next, check the stop light/CHMSL fuses on the truck. On a newer truck it is unlikely that fuses would be blown or missing but its easy enough to check. When a brake controller is not working with the brake pedal it usually means there is an issue on the red wire. With the brake controller plugged in and the fuses good though the only other thing

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. I do typically recommend going with a proportional brake controller, which uses gyroscopes and sensors
