Video Transcript for Tekonsha BRAKE-EVN Trailer Brake Controller: The Breakdown

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at this Tekonsha BRAKE-EVN proportional, trailer brake controller for one to four axles. Now, this brake controller activates your trailer brakes in proportion to your vehicle's braking action. It automatically adjust your trailer's braking based on the deceleration of your tow vehicle. And it activates immediately.

There's no pausing like with time delayed brake controllers. This controller will work with trailers up to four axles or eight brake assemblies. And it is designed for use with electric brakes only. Now, it automatically levels. The internal sensor detects deceleration even if the controller is not mounted level.

And it can be mounted at angles between -20 degrees and 70 degrees in the vertical plane. The boost setting is going to let you adjust the aggressiveness with which the brakes are activated. You can get full power output faster by pressing the plus button, as you see right here, to increase that activation speed, or achieve smoother braking by pressing the minus button that you see there to supply power gradually. This also has a built-in slide bar manual override. Now, this features an easy to read LED display to keep you informed of your trailer's braking.

The display is gonna show the gain setting when the control is activated. And it can also be used to check for connectivity with your trailer to determine your boost setting and to troubleshoot. It is short circuit protected. And let me pull out my ruler here just to give you an idea of its size. The overall width, we are sitting right at 2 3/4 inches wide.

And then the overall length, it's probably better to measure this way. I'm trying to measure the longest points of this brake controller. We're sitting pretty close to 4 1/4 inches long. Try it up here a little bit. Yeah, about 4 1/4 inches long. And then the thickness or the height, however you'd like to describe it, we are sitting right at an inch thick or an inch tall. Now, this is gonna be a quick and easy installation. The mounting bracket, as you can see here, and the hardware to attach the bracket to your controller and the bracket to your vehicle, that is all included. A plug-in vehicle specific brake controller adapter, which is sold separately, can be used for certain applications to reduce installation time. It is important to note that if a custom brake control wiring adapter is not available for your vehicle, one of the following will be required. And I have that on your screen there for you. A 20 amp circuit breaker for two to four brake applications, or a 30 amp circuit breaker for two to four, I'm sorry, for six to eight brake applications. And you see those item numbers for those circuit breakers on your screen. Also, I would like to mention that if you are in need of a seven-way plug at the back of your vehicle, check out etrailer.com's exclusive seven and four-way brake control installation kit. The item number for that is on the screen as well. Now, this does have a limited lifetime warranty. And that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

This brake controller works very well. It provides smooth braking and it is easy to adjust. The first unit that we received died as soon as we tested the manual braking lever. etrailer's customer service was incredibly helpful and efficient getting us a replacement in coordination with Tekonsha technical support. That kind of customer service is hard to find. One year after purchase this unit is working well. It was a great value.

@Eddiejo That's great to hear! Thanks for the feedback. What kind of vehicle did you install it on?
by:
nice compact controller works great
by:
2019 Ford Ranger
Installed on a 2019 Ford Ranger with factory 4 pin connector, no tow package.
To save others time here is what i found out while trying to wire this in. Disconnect the negative battery or you may blow 2 fuses while doing this.
There should be 4 wires under the dash bundled together with heat shrink on them.
They will be Blue, Yellow with Red tracer, White, and Purple with White tracer.
Blue is trailer brakes, Yellow/red is batt+, White is ground, Purple/White is brake light switch.

We used this to pull an 18 foot camper through 3 states and back home again. Then we pulled the camper the following year through 2 states and back home again. Steep hills and mountains and hairpin turns were part of our route and this brake controller worked perfectly. Braking was easy and smoothe. Pulling vehicle was a 2022 Toyota Tacoma SR5.

Poor value and customer service. You sold me a brake controller that does not fit the car's plug. You don't have an adapter, so I have a worthless item. You want me to pay the return postage. This will be my last order with e-trailer.

Hey Pam. Some vehicles are equipped with a plug under the dash area. I looked into your vehicle and it looks like your specific vehicle does not have that feature. Since there isn't one available, you would need to get # ETBC7 to complete the install.

The wiring adapter connected properly to my truck's factory, wiring adapter for electric trailer brake controller. It also subsequently connected properly to the Tekonsha Brake EVN electric brake controller I also purchased from etrailer. Everything worked properly towing my trailer.

I own an old Dodge pickup (1996) that I've used for 20 years to pull my RV. It had an aftermarket non-proportional brake controller that worked, but did not provide a very smooth braking experience. I finally got smart and started investigating whether or not there was any brake controllers that would work better. A visit to eTrailer and a little research led me to this unit. I only tow one trailer with electric brakes, so I had no need for fancier units that would remember different trailers. Because my truck is so old, eTrailer didn't have a plug-in harness for it, but I didn't have any problems with cutting off the plug and directly attaching to the wiring that was run to the old controller.

So far I've only towed a short distance with this new controller, but I am very happy with how well it works. Coming to a smooth stop is much, much easier than with my old non-proportional controller. This one is easy to set up and use, so I'm a happy camper! I just wish I had realized this was available years ago.

Sorry you didn't make the swap sooner Robert, but I am happy to hear that you feel such a difference with the proportional brake controller over those old time delayed ones! The time delayed ones were great when they were the only thing available, no more jerky stopping. What kind of camper do you have? Did you go on any fun adventures this year, or have any big ones planned for next year? I would love to hear about them =)

2018 Toyota Highlander
This addressed the problem with a 2018 Highlander (generating error codes) when connected to the brake switch. Could have done the same for a dollar or two by installing a diode in the signal line, but this adds the convenience of the whole harness and connector. Works well
by:
I chose to use this harness instead of the one that came with the Takonsha P3 because it’s slightly longer and it has a shroud so it looks nicer than a bundle of wires—especially when we stow the P3. We just tuck the connector behind the P3’s bracket.
by:
It was fine although I did not need it since after installing, I open the brake controller box to find another wiring harness exactly like the one I paid extra for. I assume the salesperson did not know the controller came with a harness.
by:
Installation was straightforward and worked well. I am a believer in electric brake controllers!

2011 Ford F-150
During conversion of the 2011 F150 from factory flat-4 to 7-blade, I had already wired for a brake controller, so installation was very simple. I've only towed once since installation, but initial setup was easy and it brakes very smoothly. Great product.

Insulation was easy and the unit looks good installed. I have not used it pulling a trailer, so I can’t speak to the operation, yet.

  • What Does Reese Brake Conroller ER Code Mean
    An ER code on a brake controller indicates an internal problem and would mean it's time to replace it. For a replacement the Brake EVN # TK63VR is a very reliable and better performing controller than the Reese you have now.

  • Troubleshooting Trailer Brake Assemblies that Are New But Not Strong
    Since you mentioned that your brakes are brand new it's very likely you have a set of self-adjusting brake assemblies that just haven't adjusted fully to the point of activating strongly. This is a very common problem actually and has a very easy solution. What you'll want to do is find somewhere you can tow your trailer slowly like an empty parking lot and the manual override lever of the brake controller several times. Each time you apply the override the assemblies will tighten slightly...

  • My Vehicle has a 4-Pin Trailer Plug, but Trailer has 7-Pin Trailer Plug
    If you just need a 4-pin to 7-pin trailer wiring adapter, then you can use part # C57672. This will plug into the 4-pin trailer connector on your brother's vehicle and give him the 7-pin socket for the trailer. Keep in mind, this will only give you trailer light functions. If your trailer has a 7-pin connector, then it likely has electric trailer brakes and an onboard battery. If you want a fully functioning 7-way trailer socket on his vehicle, then the installation will be a bit more...

    It sounds like you installed the Draw-Tite Activator Trailer Brake Controller 5100 in a vehicle with an integrated factory brake controller. If that is the case, installing an aftermarket brake controller like the Activator will cause the instrument cluster to flash the error code you mentioned. While this can be annoying to look at, it does not interfere with proper functioning of the aftermarket brake controller. The only way to clear the code is to take the vehicle to your local dealer...

  • Can Trailer Brakes be Wired Directly to Brake Light Circuit
    If you connect the trailer brake light circuit to the trailer brake circuit your brakes would lock up immediately since 12 volts is max braking voltage for trailer brakes. You'd need a brake controller that can vary voltage so that you can apply the brakes in a smooth way. The Brake EVN # TK63VR is a great choice for this as it has an internal sensor that applies can tell how hard you are applying the vehicle brakes and applies a similar amount of brake pressure to the trailer brakes.

  • Suspension Enhancement Recommendation for 2008 Toyota Sequoia Towing Trailer
    The Timbren kit part # TTORSEQ1 that you referenced is the correct fit for your 2008 Toyota Sequoia and would give you additional suspension support when towing. That said I wouldn't necessarily recommend this kit unless you were planning to be towing most of the time as it would make the ride quality a bit harsher when not towing.

  • What Does ER Code of Reese Brake Controller Indicate
    The ER code on a Reese brake controller typically indicates an internal problem that can't be fixed and requires replacing the controller. Since yours is still working normal I'd say that you are probably on borrowed time with it and will eventually need a new one once it decides to fully let go. When it's time the # TK63VR is a really great choice that is proportional (senses how hard you are applying the vehicle brakes) and priced great. This would plug right into the harness you have...

  • Could Draw Tite Brake Controller Cause Vehicle Battery to Drain
    It really shouldn't be the controller under normal circumstances. The brake controllers like the Brake EVN # TK63VR go into a sleep mode after several minutes of inactivity which would prevent battery drain. Also the small LED light of the controller wouldn't be able to drain a battery in a matter of a couple days. If the controller is staying active that could be caused by shorts on the wiring of the controller to the vehicle or even a short or corrosion on the 7-way connector. You could...

  • ABS Error Warning Light on 2018 Toyota Highlander When Installing Trailer Brake Controller
    In order to prevent the ABS error on a 2018 Toyota Highlander when hooking up a trailer brake controller to the stop light switch circuit you need the Pigtail Wiring Harness with Diode for Tekonsha and Draw-Tite Brake Controllers part # 7865 which has an in-line diode to prevent the error. This harness is designed for use with Reese, Tekonsha, and Draw-Tite trailer brake controller such as the Tekonsha Primus IQ Trailer Brake Controller part # TK90160 which is what I recommend.

  • Attaching Brake Controller Install Harness 7865 to Tekonsha Voyager
    You'd just have to cut the connector your Voyager has now off so that you can hardwire the # 7865 to it matching color for color since yours was already cut and wired. We don't have a harness that fits to factory wiring of your vehicle.

    The Pigtail Wiring Harness with Diode for Tekonsha and Draw-Tite Brake Controllers part # 7865 is required for a 2019 Toyota Highlander no matter which trailer connector or brake controller you're using as the diode is on the stop light switch connection which splices into the vehicle's brake pedal.

  • Solution For Brake Controller EBS/Error Message On 2020 Toyota 4Runner
    This is a common issue I've seen in many different Toyota 4Runners as they seem to be more sensitive to backfeeding from the red wire of the brake controller to the stop light switch. This causes the issue you're seeing, triggering the ABS error message. You are correct when thinking that a diode will prevent this from happening but the Tekonsha 3041-P harness does not feature a diode in the red wire; the harness you need is the # 7865.

The only way to prevent this is to use the a diode with the harness and the Pigtail Harness # 7865 offers a perfect solution as it features a diode on the red wire.

  • Brake Controller that Works with Emergency Braking of 2019 Ford Ranger
    I have a similar brake controller solution that does work with the emergency braking system of your 2019 Ford Ranger with the P2 part # 90885 and the diode kit part # 7865 but Redarc doesn't have a diode kit yet to allow the Tow Pro Elite part # RED44FR to work. This controller will work a lot better than any OEM controller for sure.

  • Wiring Needed To Install A Tekonsha Trailer Brake Controller On A 1991 Ford F-450 Cab & Chassis
    If you have a Tekonsha Trailer Brake Controller like # 90885, trailer wiring is needed and you found a good universal 7 pole wiring kit # ETBC7. Once that is installed you can install your Tekonsha Brake controller. If you bought the Prodigy P2 it should have came with the # 7865 connector, but if not the # 7865 is what you need. I've included a bunch of videos for you to watch to help with the install!

  • Recommended Trailer Brake Controller and Weight Distribution Hitch For 2017 Toyota Highlander
    I would be happy to help! Starting with the trailer brake controller you will need to first have a 7-way trailer connector installed on your 2017 Toyota Highlander XLE.

The Curt hitch is compatible with your Limited model and comes with all mounting hardware required for a bolt-on installation. As far as weight capacity, the hitch has a 500 pound maximum tongue weight and a 5,000 pound gross towing rating.

  • Parts Needed To Install Draw-Tite I-Stop IQ In 2021 Toyota Highlander.
    I am happy to help! You are correct that your 2021 Toyota Highlander does not have a factory trailer brake controller port, so you will need to use Pigtail Wiring Harness with Diode for Tekonsha and Draw-Tite Brake Controllers # 7865. The Tekonsha Primus IQ Trailer Brake Controller - 1 to 3 Axles - Proportional # TK90160 you mentioned is the exact same controller as the Draw-Tite I-Stop IQ and will require a 20 amp circuit breaker on the power wire for the controller.

  • Brake Controller Installation on 2018 Toyota Highlander
    You'll need to choose a brake controller and the # ETBC7 brake controller installation kit. The install kit includes an adapter to convert the 4 pole you recently installed to a 7-way. I'd recommend a proportional controller like the Tekonsha Primus, part # TK90160. Your Highlander is very sensitive to power feeding back into the brake lamp circuit, so instead of the pigtail included with the Primus, you'd need to use the # 7865 which has a diode installed on the brake lamp circuit to...

  • Recommendation for Installing Draw-Tite Brake Controller in 2018 Ford F-550XL Truck
    If the 2018 F550 Cab and Chassis has a factory 7-way on it, then you will be able to simply use wiring harness # 22292 to work with the Draw-Tite Activator IV # 5504. If you have the factory 4-way flat, then you will use that same harness, but will also use # 37185 to connect to the vehicle's tow package wires found along the rear frame rail. If it does not have any wiring, then you will need # 18252 to add the 4-way and then use # ETBC7 to complete the wiring for your controller which...
