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:
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 beneath 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. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.
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.

initially had trouble finding the Toyota connector since there was an unidentified cover on it but worked well after locating it
Using the Curt wiring adapter, installing the Curt TriFlex brake control in my 2006 Toyota Tundra was simple after watching your video. Very pleased with everything I ordered from e trailer.
I’ve owned 5 brake controllers. This is the only one I’ve disliked. This controller has non digital controls (should have been my first clue it might not be good) it just has two slide controls. Problem is two things, the slide controls themselves are black, the same color as the case on the unit and you can’t even see the position of the slide controls because they blend in with the color of the case. It’s impossible to tell if they’re turned down all the way, turned up all the way, in the middle? The other problem is that the slides are so imprecise, They slide way too easily and there’s no detents and I found if you even bump the unit slightly or are going over rough roads the slide switches migrate. I was towing a couple of weeks ago and I thought I had the switches dialed in as good as I could, I was on some rough roads, due to road construction in the area, the output switch vibrated over to maximum and the next time I hit the brakes , the trailer locked up completely. So I had to turn it off until I could get to the next town where there was a parking lot I could readjust. I’m definitely getting rid of this thing and I definitely recommend you do not buy it. Buy something with digital output controls so you know precisely where the settings are. I firmly believe this controller is dangerous and I know if I keep using it I’m going to get an accident.
plug in to factory harness without cutting orvsplicing. saved a couple hours working under dash. worth the cost. unfortunatelt harness adapter, brake controller or some other fault is causing random trailer brake lock-up without applying vehicle brakes at highway speeds, a scary event. unable to troubleshoot as winter snow then heart health issue continue to prevent me from moving trailer to troubleshoot.
Yes I received my order and installed the brake controller. All seems to be
fine, although I have yet to tow with it yet. Here are a couple photos of
the installation in my 2010 Toyota Tundra.
The package was shipped and received 2 days early. It was delivered in perfect shape. I think I will be happy with this brake controller!
Using the harness is the best and easiest way to install a brake controller. The warranty on the controller is still valid since no wires have to be cut.
Took about 10 minutes to install. Have not made all the adjustments yet, but is easy to understand.
Installed on 2011 Toyota Sequoia - Plug and play as advertised.
Made the install of the brake controller straight forward.
Tested . Work fine and advertised
Pending installation…
Well that was the easiest thing I've ever done on a vehicle. The info on the etrailer site was instrumental in this being a quick plug-n-play mount of the Curt brake controller. I watched the two minute video and 10 minutes later I had a new brake controller installed in my 2010 Tundra.
Teconsha P3 is an excellent brake controller.
Even better was the customer service from etrailer....I had an issue with another model, called etrailer, and they made it right. No questions asked. Will definitely shop with them again. Thanks, etrailer! -wade

Love the Tekonsha. Will not buy another Curt. Thanks for asking. And e-trailer was great, especially dealing with the dysfunctional Curt. Thanks.
I installed the Curt TriFlex Brake Controller C51140 along with Wiring Adapter C51362 on my 2012 Tundra. Was super easy. Thanks for video.

Perfect. No issues at all.
The wiring adapter was easy to connect and tuck up under the steering wheel to attach to the brake controller.
Fit like a glove
This wiring adapter fit perfect between the Curt Adventurer brake controller and the pigtail harness in my '06 Tundra. Remove the truck's driver side kick panel, cut the truck connector loose from where it was secured, and plug this adapter into both the truck and the brake controller. Plug and play.
excellent service and delivery.
Great service!
Custom cable made my brake controller installation a simple project. Fit perfectly and took all stress out of the job. I would buy again without hesitation.

Yup, still working as supposed to. No complaints. Well worth the money.
The adapter for connecting the trailer brake controller arrived earlier than scheduled. It enabled a quick and easy plug and play connection of the controller to the vehicle.

Worked perfectly - plug and play
Fast shipping! Great product for this price. My 2012 Tundra has airbag underneath steering column so I mounted brake controller just left of area.....perfect! Works like it came stock.

Outstandingly
Works well, easy to install. Sometimes the lights do not go off. I have to restart the 2017 4Runner and wait for them to go off.
