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.
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
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: C51436
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 behind 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 behind 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 behind the dash.
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.

Kate M. my salesperson, had a most professional interaction with me being certain of my and my vehicle's needs. In addition, she walked me through the complete installation process. This I completed, wiring the 7-way and the Curt Discovery Controller making no errors along the way. On the first test, every terminal on the 7-way tested as it should. When we came home with the RV from the dealer, all the lights and the brakes worked flawlessly. Many thanks!!

2010 FordF-150
The cable assembly made installation quick and easy, all I had to do was locate the Ford supplied connector in my F150. The cable assembly supplied by Curt plugs into the Ford provided connector. Plug the opposite end of the Curt supplied cable into the controller and the electrical installation is complete. Note: the Ford supplied connector has a protective cover on it, you have to remove this cover before this Curt connector will plug in.

Excellent - no hesitation in making that evaluation
I bought a brake controller, interface cable for the F150, and the 7 pin plug that goes on the back bumper. All items are great quality. Parts arrived as expected with shipping as paid for. I am installing the equipment, but don't have any issues. There were no installation instructions, however these are available on line line detail. I do not expect any operational probems but am a few days from making that test.

Etrailer provided outstanding information regarding the technical details of the product along with easy to understand installation instructions. The brake controller provided a cost effective solution for my basic requirements. The installation was a "snap", the only time consuming task was determining the optimal location/position install the brake controller. Item was installed in a 2013 Ford F150 and I use it on a dual axle trailer for hauling a compact Kubota tractor.

- I will be happy to clear up what all you will need to add the equipment to tow the trailer and activate the electric brakes.
First, if your 2004 Nissan Xterra does not already have a trailer hitch you will need to add one. A popular option is Curt trailer hitch # 13183. This is a Class III hitch with a 2 inch receiver. The hitch itself is rated for 400 pounds tongue weight and 4,000 pounds gross trailer weight but limited to the vehicle capacity if lower.

view full answer... - 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.

- Yes. You could use the Curt Discovery # C84VV on your 2021 Honda Pilot with the plug and play adapter # C51392 to allow for an easier installation that won't require cutting into any wiring. 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

view full answer... - Why Is Stoplight Circuit Difficult to Find on 2017 Ram 1500 For Installing Brake Controller
- Your generation of Ram truck uses a powernet style of wiring at the brake switch wiring which means the voltage will actually read lower than what a 12 volt circuit tester is going to show. Also if you are trying to hardwire a controller you are going to have issues as we've found that if you don't use a harness designed specifically for your truck's wiring setup you may damage the vehicle.

- Between the two controller I would go with the proportional Curt Triflex part # C51140 over the time delayed Curt Discovery part # C84VV.
A time delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, a time-delayed controller sends

- It is possible that on your 2009 Volkswagen Tiguan you will need to follow the alternate installation instructions for the Touareg. I have included a link to an article that explains this.
That would be if you are unable to locate a proper dedicated brake light only circuit. The first place to check is above the brake pedal. Look for a brake switch with wires going in and out of it. Use a circuit tester such as # PTW2993 to probe the wires (the key may have to be in the on position).

- The OEM brake controller requires your 2021 Ford F-150 to be flashed by the dealer.

You will need Plug-In Wiring Adapter # C51436 to connect the brake controller to the factory plug-in on your truck.
