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. Use the arrow buttons on the front of the module to set the output. You want to set the braking output as high as you can without locking up the brakes. Once you've set up the brake controller the first time, you shouldn't need to adjust this setting unless the trailer load changes, you switch trailers, or road conditions change. The LCD display will show the current output setting being used.
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. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.
Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set braking output. What this means is that, instead of starting at 0, the brakes will start at 25 percent and get to100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.
If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.
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.
Storable Settings
Customize the P3 and store your settings so that you can easily access them later. If you tow multiple trailers, or the same one but with differing loads, store the desired boost and power levels for each so that you don't have to completely reset the controller every time you switch between trailers. It's easy to swap between drivers as well. Program the P3 display with your desired screen color, brightness, and language, and you can easily return it to your preferred settings the next time you tow.
Customizable LCD Display and Advanced Diagnostics
The P3's LCD display features a distinctive look with multiple color and contrast options. With lots of customized options, you can change the display to make it easy for you to see and check your braking status at a glance.

It also includes comprehensible and detailed roadside diagnostics. The P3 advanced diagnostics not only notify you of potential problems, but they can also tell you where to begin troubleshooting.

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 will be in power-saving mode. In this setting, it draws only 3.6 milliamps, minimizing drain on your vehicle's battery.
The P3 also comes equipped with a hold feature to prevent wear on your brakes. When you're waiting at a red light, you don't need your trailer brakes on at full power. The longer you sit there, the more they will overheat. But with the P3, any time your tow 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 while saving your brakes.
The P3 keeps the manual override within easy reach, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just twist the rotary-style lever from right to left. 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.
Automatic Leveling and Simple Installation
The self-leveling feature of the P3 ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at any vertical angle, and the controller will level itself automatically thanks to its 360-degree rotational range. This makes the installation that much easier. But keep in mind that the P3 must be horizontally level and parallel with the direction of travel to work correctly.

Installation is a snap. After mounting the P3 unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To remove the P3 for storage when you're not using it, just unplug the unit and slide it out of the bracket. With a replacement wiring harness (sold separately) and replacement bracket (TK5906 - sold separately), you can even transfer the Prodigy P3 to another vehicle.

Installation Accessories
For even easier installation, a vehicle-specific specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

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
Proportional Braking
![What is proportional Braking]()
The Tekonsha Prodigy P3 brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, 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's braking. This saves wear and tear on the tires and the brakes on both 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.
