Braking Output

Tekonsha Prodigy P3 brake controller

Braking output is the maximum amount of power that will be applied to your trailer's brakes. 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.


Use the arrow buttons on the front of the module to set the output.


Power Boost for Heavy-Duty Towing

The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, decrease the setting.


Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set braking output. So instead of starting at 0, the brakes will start at 25 percent and get to 100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.


Boost Levels:

Approximate Gross Trailer Weight Boost Level Increase in Initial Power Output
Less than tow vehicle GVW B1 13%
Equal to tow vehicle GVW B1 or B2 13% or 25%
Up to 25% more than tow vehicle GVW B2 or B3* 25%
Up to 40% more than tow vehicle GVW B3* 25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.


Manual Override

To engage the manual override, twist the rotary-style lever from right to left. This will activate the trailer's brakes and brake lights independently of your vehicle, great for stopping sway or controlling your trailer's momentum in an emergency.


Save Your Settings in Multiple Profiles

The P3 is able to store your settings in multiple profiles so that you can have them ready to go for different trailers and drivers. Even the display is super customizable: you can change the screen color, brightness, and language to make it easy to use.

Safety Features

The Prodigy P3 offers advanced safety features to prevent damage to various components of your towing setup.


-Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts.


-When the P3 is not in use, it draws only 3.6 milliamps, minimizing drain on your vehicle's battery.


-Any time your vehicle and trailer are at a standstill with the brakes applied for more than 5 seconds, the hold feature will kick on and reduce power to just 25 percent. This will keep your trailer in place without your brakes overheating.


Installing the Tekonsha P3

Installing the P3 is incredibly simple. You'll mount the bracket to your dashboard then mount the unit to the bracket. Plug the custom harness into your vehicle and into the unit. Done!


Keep in mind that the P3 must be horizontally level and parallel with the direction of travel to work correctly.

With a replacement wiring harness (sold separately) and replacement bracket (TK5906 - sold separately), you can even transfer the Prodigy P3 to another vehicle.

Note: If you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake controller installation kit (ETBC7 - sold separately).


What is Proportional Braking?

What is proportional Braking

Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle and trailer.


The Prodigy P3 uses an internal inertia sensor to detect how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Video Transcript for Choosing Between Tekonsha Brake Controllers

When it comes to choosing a brake controller, a lot of them are gonna look very much the same. And two of them that I really like are from Tekonsha. We have the Prodigy P2 and the Prodigy P3. So, they look very similar, but they do have quite a few differences and we're hoping to break that down, that way you can decide which one's best for you. Here we have our P3 installed and really it comes down to it has more bells and whistles than the P2, otherwise it's pretty much the same controller. The P3 does have a nicer/easier to use display.

It's a little bit more user friendly. It uses some icons here that, you know, show you a trailer and that way you know pretty quickly what boost level you're at and it's really easy to read. It's a nice digital display and you can change a lot of that. Also, it has a little bit more diagnostics. So as far as, instead of just having error code with the P2, this one will actually tell you exactly what it is and there's a host of diagnostics so that way you can look at it.

You won't have to troubleshoot the code by looking at the owner's manual. It'll tell you right away what's happening. The P3 is also really nice if you have a bunch of trailers in your fleet, you can set up presets, up to five of 'em, and that way when you hook up to said trailer, you can select that and it's gonna be preset to the boost settings and also the gain that you may have dialed in. That way you just hook up and you'll be ready to go. Multiple trailer settings are gonna be nice, especially if you have a work truck and you're hooking up to a bunch of different trailers, you can get that dialed in, but if you tow the same trailer over and over, or you know that you're only gonna have one trailer long term or maybe two, that's really not gonna be a function that is necessary.

Now with the P2 installed, you can see right away that the display is obviously not as fancy as the P3, but you again have all the same functionality. There are less buttons, so that kind of keeps it simple. If you just need a brake controller, this is a great option. You still have your power knob, you have your boost button, and you still have essentially the same manual override, which I do like on the Tekonshas, you have a nice modulation here. But really when it boils down to it, they are very, very similar.

The size is gonna be almost identical. They're gonna mount up the same, they're gonna install the same. Again, you have that same proportional here. They both work for one to four axles. They're both proportional. So pretty much the same thing, just more bells and whistles on the P3. If it's something that you're gonna wanna keep for a long time on your vehicle, a P3 is pretty sharp. I do like the display, and something to think about too, you can always take a brake controller from one vehicle to the next, so, but if you're just need to tow a trailer and you need a brake controller, P2 you're not gonna go wrong with. I just like the fact that there is diagnostics that are a little bit more straightforward with the P3. And if you're worried about if it's gonna work with your trailer, they're both gonna work with the same kinds of trailers. You can have electric brakes, you can have hydraulic brakes, it doesn't matter. These are gonna work with either one. So hopefully this video helps break down some of the similarities and differences to help you decide which Tekonsha Prodigy Brake Controller is gonna be best for your needs.

  • Can I Add Electric Brakes To A 1993 EZ Loader Boat Trailer
    Hello Mike. It sounds like you are wanting to add electric brakes to your boat trailer that currently has no brakes. This is possible, but you will first need to make sure that your axle is equipped with a brake flange at the base of the spindle. The brake flange is necessary for adding brakes. If you do have a brake flange, you will next need to determine your bearing sizes. Electric brakes will require new hubs and drum assemblies, and we need to be sure that there is a drum available...

  • Will The Curt Echo Manual Override Button C83HR Work Without The App?
    Hey John, good question. The app must be running in order for the separate manual override button part # C83HR to work. If your phone is not connected to the controller with the app running, the button will not do anything. I know the connectivity issues can be frustrating, but it might not necessarily be something you are doing wrong so much as the controller just being unreliable. This is by far the most common complaint we get about the Curt Echo # C51180 wireless controller. Most...

  • Difference Between Curt & Draw-Tite Trailer Hitches For 2018 Jeep Wrangler Unlimited
    Hi Ken, Starting with the wiring harness, I can verify for you the correct fit for the 2018 Jeep Wrangler Unlimited without a tow package is indeed the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. Then for the hitches, the biggest difference between the Curt Trailer Hitch Receiver # C13392 and Draw-Tite Trailer Hitch Receiver # DT78MR is the length of the receiver. The Draw-Tite has a shorter receiver that can make it a bit more of a pain to add a ball mount...

    There are a few differences between the Universal Installation Kit part # ETBC7 and the 7-Way RV Upgrade Kit part # ETBC7L.

The reason for this is because part # ETBC7L is geared more towards wireless brake controllers like the Curt Echo Mobile Trailer Brake Controller part...

  • No Trailer Connection on Tekonsha P3 Brake Controller 90195 on a 2000 Toyota Tundra
    I would start by inspecting the connector on your trailer and the vehicle to make sure there is not corrosion in the connector which could be causing a bad or weak connection. If there is corrosion in the trailer side connector, you would need to replace it with 7-way Connector, part # A7WCB. For the replacement vehicle side connector, you would need Adapter 4 Pole to 7 Pole, part # 30717. For future use, I would recommend using Dielectric Grease for Electrical Connectors, part # 11755,...

  • Recommended Trailer Brake Controller and Wiring Needed for 2000 Toyota 4Runner
    For your 2000 Toyota 4Runner, I recommend the Tekonsha Voyager Trailer Brake Controller - 1 to 4 Axles - Proportional # 39510 with the Brake Control Plug-In Harness # 20127. This is the best controller under the price point you are seeking. Then for your wiring, if you already have a 7-way connector you can use the kit # 5506. If you have a 4-way then you will use the # ETBC7 kit which comes with the 7-way adapter and wiring. If you don't have a 4-way, then you will need that first and...

  • Location of Factory Trailer Brake Controller Harness on a 2007 Toyota Tacoma with Tow Package
    The factory harness to plug in a brake controller wiring harness on your 2007 Toyota Tacoma is located underneath and left of the steering column, taped to another harness near the emergency brake pedal. There will be a 5-pin connector that mates with the one on the adapter, # 3040-P. The harness does include an additional ground (white) wire that will need to be attached to a bare metal surface. The P2 is a proportional controller that applies the trailer brakes in proportion to how much...

  • 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. The better option if you are concerned about ride quality is the part # F4164 which allows you to use varying air pressure in the bag so that you can tailor...

  • Brake Controller Installation in 2015 Toyota Tacoma
    The # 3040-P is indeed the correct brake control wiring adapter for your 2015 Tacoma. Due to the presence of the knee airbag, the preferred location to the right of the steering column might not be feasible. If there's not a suitable location to the right of the steering column where the controller could be mounted so that it's parallel to the direction of travel, you'll need to consider an alternate spot. If you watch one of the videos I've linked you to, you can see the controller being...

  • Location Of Brake Controller Connector In 2003 Toyota Land Cruiser
    If your Land Cruiser was equipped with the factory installed 7-way trailer connector at the rear bumper, it will have the brake controller connector located under the dashboard. The connector will be taped to another wiring harness somewhere near the top of the emergency brake pedal. The connector will likely be covered with tape, so it could be difficult to locate. If you find a big ball of tape wrapped around a wiring harness, you've probably found it. The # 3040-P you've referenced is...

  • Where to Connect Brake Controller Adapter in on a 2014 Toyota Tacoma with Factory 7-Way
    If your 2014 Toyota Tacoma came with the Factory 7-Way then you will want to look next to the driver side kick panel for the wiring harness.

  • What Parts are Need to Install a 7-Way on a 2007 Toyota Tundra

  • Recommended Brake Controller for 2007 Toyota 4Runner with Weight Distribution System Sway Control
    For your 2007 Toyota 4Runner, the Prodigy P3 # 90195 is what I recommend for your brake controller. If you have the factory 7-way, then you will simply use wiring harness # 3040-P and you'll be ready to go. If you don't have the factory 7-way then you will need to hardwire the controller using # 5506 if you have a 7-way or # ETBC7 if you need to add a 7-way. I've attached a couple videos to assist.

  • Equalizer or Blue Ox Weight Distribution for 7,500 lb Trailer
    Between Equalizer and Blue Ox I would go with the Equalizer hands down. Equalizer systems are among the nicest systems you can use. The Blue Ox systems work decently but in terms of sway reduction, ease of install, and reliability the Equalizer is the way to go. You would want the part # EQ37120ET which would work great on your trailer that weighs 7,500 lbs. It comes with a hitch ball but you would need the thin walled socket part # ALL643216 to install it.

  • Will LED Light on TK63VR Tekonsha BRAKE-EVN Drain Vehicle Battery?
    Brake controllers like your Tekonsha # TK63VR are wired so that they have a direct connection to the vehicle battery. This is done as a safety measure, so the user doesn't accidently forget to turn on the brake controller when towing. After a between 10 and 20 minutes of inactivity, a brake controller will go into a sleep mode, where they are just about completely powered down. At this point the amount of power they draw is so tiny that you'd need to leave the vehicle unattended for a...

  • Will Adapter 4-Pole to 7-Pole and 4-Pole Connect To Brake Output Circuit on 2013 Toyota Tundra
    Hi Dana; does your 2013 Toyota Tundra have the brake controller port under the dash? If it does, you can use the # TK77ER along with the # 37185. There will be factory wiring, including the brake output wire, you can splice the # 37185 into at the rear.
