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.

Specs:
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.
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.
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.
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.
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.
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.
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:
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.

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.
Took about 10 minutes to install. Have not made all the adjustments yet, but is easy to understand.
Tested . Work fine and advertised
excellent service and delivery.
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.
Brake controller and adaptor installed and connected in less than 10 minutes, I am very happy with the purchase and the included instructions and information.
Product installed in 5 minutes, tested and setup in 10 minutes. Shipping was fast. Superb value

Works great
This product was perfect for my use. The wiring harness worked just as I was told and very easy to install. I have bought several items from etrailer and everything has been good quality. The items arrive in good working working condition and in a timely manner.
Etrailer employees are very helpful and professional.
Perfect, plug and play
This is the second of these units I have purchased and installed. The quick connect ends make it soooo easy, just plug the matching ends together (NO splicing wires). I highly recommended this unit with the pigtail extender
Product fit just like it should and as you said and your video or picture was very helpful in finding the plugin at such a weird location that ford put it.

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.
I haven't installed it yet but it looks fine to me
Very nice. Everything fit perfect
Couldn't have been easier to install.

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.
