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: C51432
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, which is located behind the dashboard. To access this connector, you will need to remove the finish panel in your dash. Plug the adapter into the connector in the large gray housing behind the panel.
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 believe I entered the correct vehicle type and the cord did not match my 2024 e350 super duty. Luckily there were extra wiring harnesses with the new van. I spliced the correct end that matched my brake controller left behind my coin tray by the manufacturer. I was able to use the rest of the harness to the brake controller so it still was useful. Who knows. My manufacturer could have wired it incorrectly.

I bought a weight distribution hitch w|sway control, and a trailer brake controller for my Four Winds RV. I received my order today, within a few days of placing the order. I have not installed it yet but it appears to be user friendly. Both pieces are made by Curt so the quality & performance should be good.
My thanks to etrailer & Stacy??

Ford 2013 F250.. This brake controller fit like a glove. I have a 2013 F250 and I finally found the plug behind the coin box on the dash. It fit just right and after I finally found where the factory plug was and routed all the wiring behind the dash it took about about 15 minutes to get everything working. I have use e-trailer for several projects and the shipping is amazing and they totally understand what they are doing. Thanks to all at e-trailer.

I recently bought a Kurt trailer brake controller with adaptor. I have to say, that it was the easiest thing to hook up. The product was also shipped to my home very fast. I did not think I was going to receive the package until the next week, but it came just in time to use it the following day for my work. i Love ordering products from etrailer, I have only had really great service and good products from them. I will for sure, order from them again.

I see that you ordered the C51140 brake controller with the C51432 adapter. Since you said you have a factory 7 way, the adapter will plug into the built-in port behind your vehicles dash. If you cannot find the built-in port and are not sure if you have a factory 7 way, you can call a local dealer with your vin number and they will tell you. Please note, if your vehicles 7-Way trailer connector has LED test lights built into it, the TriFlex brake controller will not be compatible.

First of all I received the product much faster than expected. The gal on the phone told me a week to 10 days, I received it in about four days. It took me about 10 minutes to install it and it works perfect so far. I have no complaints about this product.

Do you have a question about this Trailer Brake Controller?
- 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

- 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

- To install the Curt Discovery Trailer Brake Controller # C84VV on your 2005 Ford F-150 you will need the Curt Custom Wiring Adapter # C51322.
This connector will be found under the dash on your driver side. I have attached a video of this adapter being used to install the Curt Venturer on a 2004 F-250 that you can use as a reference.

If you have a 4-way connector installed on your Tundra, part # C51515 is what you need. This harness is used on a vehicle that does not have a factory tow package or on one that has a brake control harness but is not equipped with a plug-in port. If your vehicle doesn't have a factory tow
view full answer... - Troubleshooting No Power on Blue Wire After Installing Curt Discovery Brake Controller
- The issue you're describing likely has to do with the red brake input wire coming from the Curt Discovery Brake Controller # C84VV and corresponding harness # C51515.
You will want to make sure that this red wire is connected to the cold side of the brake light switch behind the Suburban's brake pedal. This is the wire that ONLY gets power when the brake pedal is depressed and no power with any other function. I recommend using a circuit tester like # PTW2993 to verify you have found

- The troubleshooting guide included in the instructions for the Curt Discovery Brake Controller # C84VV that you referenced does not include this particular display issue, a flashing 0.0, among the possible display messages.
My technical contact at Curt has never seen this particular message displayed on a Discovery brake controller. He suggested that either the display is malfunctioning or the controller is bad. Since your brakes are not engaging when you press the pedal with the trailer

- There will be no need for you to go to take your 2015 Ford F-150 to the dealer to have them turn on an aftermarket brake controller. The brake controller I recommend that you need only an adapter for is the Curt Discovery # C84VV.
Since you already have the factory tow package, just use the Plug-In Wiring Adapter # C51436.
Plug one side into the brake controller and the other side into the wiring on your F-150 and you are done.

view full answer... - Can Curt Discovery Brake Controller be Installed 2015 Hyundai Santa Fe
- Yes, you can install the Curt Discovery brake controller part # C84VV in your 2015 Hyundai Santa Fe. You will also need the harness part # C51515 to give you 4 wires to then wire to your vehicle.
You will need to start with a 4-way (if you do not have one). For that you would want the # C56332.
From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7.

- Thank you for your recent purchases from etrailer.
I would like to suggest some additional testing before you return the Curt Discovery Trailer Brake Controller # C84VV. This will help isolate the problem and confirm whether the unit is indeed defective.
The code OL indicates that the controller has sensed an overload condition. Disconnect the trailer from the Tahoe. Apply your grounded tester to the pins at the 5-o-clock and 7-o-clock positions on the Tahoe 7-way, as shown on the

- If your 2008 Toyota Tacoma has a factory 7-way, the only thing you will need to install the Curt Discovery Trailer Brake Controller # C84VV is the Curt Custom Wiring Adapter # C51362 which will plug into the port underneath the dash of your '08 Tacoma.
If your truck does NOT have the factory 7-way you would need to add 4-way # 118496 along with Universal Installation Kit for Trailer Brake Controller # ETBC7. You will also need to use Universal Wiring Adapter for Curt Trailer Brake Controllers

view full answer... - Curt Discovery Brake Controller Display Flashes with Left Turn Signal
- It could be a wiring issue. Specifically, it is likely related to the brake controller red wire. If that wire is not attached to the correct circuit, it can cause some strange things to happen. The red wire needs to be connected to a brake switch wire that only has power when the brake pedal is pressed.
If that same wire has power, then the headlights or a turn signal are on then it is not the correct wire. I have heard that the correct brake switch wire is the white wire so use a circuit
view full answer... - Comparing Curt TriFlex Trailer Brake Controller To Curt Discovery Trailer Brake Controller.
- The main difference is the Curt TriFlex Trailer Brake Controller # C24VV is a proportional brake controller while the Curt Discovery Trailer Brake Controller # C84VV is a time delay controller. The proportional controller will automatically adjust power sent to your trailer brakes based on how hard you are braking, while the time delay always sends the same force no matter how soft or hard you are braking.
Those with time delay controllers will often have to reach down to crank up the
view full answer... - Curt Discovery Trailer Brake Controller # C84VV Displays Only a Red Dot After Installation
- If your Curt Discovery Trailer Brake Controller # C84VV displays only a red dot when you do NOT have a trailer connected then this indicates that the controller's red (input signal) wire is connected to the wrong side of the brake light switch. This red wire should connect to the COLD side of the switch that has power only when you press the brake pedal.
If your Discovery displays the red dot when you DO have a trailer connected then this usually indicates a problem in the trailer brake
view full answer... - Troubleshooting Flashing Display of the Curt Discovery Brake Controller part # C84VV
- The flashing O.L. message with the Curt Discovery Brake Controller part # C84VV when there is no trailer connected indicates that there is a short somewhere on the brake output circuit. I would check all the connections you made on the blue wire from the controller and then also check the trailer connector at the rear of the vehicle looking for any exposed wire or corrosion and fix as necessary.
If it only flashes O.L. when the trailer is connected the problem is the same as above but
view full answer... - Gauge Wire Recommendation for Installing Curt Discovery Brake Controller
- Curt does recommend that you use 10 gauge wire like part # 10-1-1 sold by the foot to install the Curt Discovery # C84VV, but the common recommendation for installing brake controllers is to use 12 gauge or larger wire. If you use 12 gauge wire you should be just fine, especially since you will only be activating 4 brake assemblies.

Some models with the factory 4-pole (or 4-pin) trailer connector will also have the plug under the dash, you'll need to look for a white plug located above and to the left of the emergency brake pedal, above the toe kick. Occasionally, the plug will be located
view full answer... - 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

Once the glove box is dropped, you'll see the plug next to the glove box on the left.

I have gotten in contact with the manufacturer and I see that part # C51432 (Curt Custom Wiring Adapter for Trailer Brake Controllers) is only a confirmed fit for the 2014 e350 Super Duty, not the 2024. So, it does not seem like it was your installer wiring it incorrectly. I am sending in this information to our fit guide team for them to get this corrected on our site. I am sorry for the inconvenience, let me know if there is anything I can do for you.
