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 connector behind your vehicle's dashboard. To reach the connector, first locate the notch in the access panel in the center of the dash, near the driver's side. Using a trim panel puller, carefully pry the panel out and undo the locking tabs to remove the panel. You will find the mating connector behind this portion of your dashboard.
No hardwiring is required to install this adapter. After you plug it into the 2 factory ports, 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.

Tested . Work fine and advertised
I purchased an adapter to go between my brake controller and the factory wiring in my 2015 Tundra (C51455), I have not installed it yet. I will review it when it is installed.
excellent service and delivery.
I bought this connector for my new Toyota Tacoma after moving the Brake Controller from my traded in Jeep. I had hardwired the Jeep, but this was a direct connector and was much, much easier to install. The Curt brake controller and this cable make an excellent combination to control the brakes on my Casita. The only flaw is that Toyota hides the factory end under the upper left side floor-well cover and was hard to find. Not etrailer's fault. Also, I have bought several items from etrailer and the customer service is always superb, as are all of the item descriptions and videos on the products they carry. Great place to get what you need for your vehicle.
The hardest part of the job was finding the pre-installed connector on the Tacoma. It is tucked in behind a wire bundle so you have to know where to look. Once found, simple plug and play.

Works very well.
I picked this Curt brake controller As it is specifically wired for my 2017 Toyota Tacoma which already has the tow package. When I finally found where to hook it up in my truck I realized I needed C51455 part which is the female end .. they gave me another 15 inches of extra wiring so I can mount the controller by my right leg as I drove.. and the great thing about this experience I called on a Sunday afternoon got a hold of A person ( Shawn B) Who was very helpful and knew exactly which part I needed .
I highly recommend using e trailer
VERY easy install. As mentioned in other reviews the hardest part is finding the factory plug in for a 2017 Tacoma. Toyota tucked it way in the back behind a wire bundle. Picture attached for reference.
Plug and play made install simple
Like its compact size and simple operat ion.
Very helpful, knowledgeable and friendl y!
Great service very good experience highly recommend this company
As alway, etrailer had exactly what I needed to do the job simply, effectively, and as the best price. What more can you ask for?

Flawlessly
I like this controller mainly for its sleek design and it blends into the dash of my Tacoma. It works right out of the box and I’ve rarely had to adjust the setting manually. It sometimes lights up weird when not in use but works fine. I’d purchase again.
I grabbed this cable to connect my Curt Spectrum brake controller to my 2017 Toyota Tundra tow package cable. Worked great. The Tundra cable was located immediately behind the panel to the right of the steering wheel with the auto LSD button and Tow/Haul button (if equipped). My truck had a blank instead of tow/haul button.
Ordered my brake controller for my tundra and it worked great. I had already been to a local store that kept providing me the wrong part so I took the time to research and this was exactly what I needed.
Sherry was extremely friendly and very helpful when I had questions about the correct fit for my truck. She got me the information I needed and took my order and the parts shipped the same day. I was amazed at how fast I got my order.
arrived before I expected. Finding the prewired brake plug on my 2015 tundra was a pain. This wiring adapter made it possible to complete the job.
Same review as the controller. Just plug and go. EXTREMELY easy. I had my 7 year old daughter with me and she could have basically hooked it up. She is as anxious to go camping as I am!
Was very easy to install with the vehicle specific wiring harness, took it for a short test drive with my 19 ft Scamp Camper and it works as it should
Made the install a breeze!
Product arrived on time. There was a hiccup on the item I initially ordered. They sent me a notice that it was unavailable, but I called them back and found me these comparable items for my 2015 Tundra. Items worked great and plugged right in, as well as wounted well. Overall great experience.
Excellent product
Easy install & a clean factory look in my ‘15 Tundra. Looking forward to getting a trailer hooked up to get it dialed in.
Plug and play. Has worked flawlessly for the last year thank you guys
