If you’re like me, towing a heavy trailer can sometimes feel like a white-knuckle experience, especially when it comes to stopping. There’s that moment of dread when you hit the brakes and feel the weight of the trailer pushing your vehicle. I vividly remember situations where a sudden stop was needed, and the lack of smooth, coordinated braking between my truck and the trailer made for a terrifying few seconds. This feeling of instability and potential loss of control is more than just uncomfortable; it’s a significant safety hazard that absolutely needs to be addressed. Ignoring it could lead to reduced stopping power, increased wear on your vehicle’s brakes, and potentially dangerous situations on the road.
Factors to Weigh Before Acquiring a Trailer Brake Controller
When you’re towing anything with electric brakes, a reliable trailer brake controller isn’t just a nice-to-have accessory; it’s a fundamental safety device. It ensures that your trailer’s brakes engage smoothly and effectively in conjunction with your tow vehicle’s brakes, preventing dangerous pushing or jerking motions. The ideal customer for an aftermarket controller is someone who regularly tows trailers equipped with electric brakes (like RVs, car haulers, or heavy utility trailers) using a vehicle that doesn’t have a factory-integrated system. If you only tow a very small, lightweight trailer without brakes, or if your vehicle already has a sophisticated built-in controller, you likely wouldn’t need a separate unit like the one we’re discussing. Before purchasing, consider the type of braking system (proportional vs. time-delay – proportional is generally preferred for smoother stops), the number of axles on your trailer (most controllers handle 1-4 axles), ease of installation (are vehicle-specific plug-and-play harnesses available?), the display type and information provided, the unit’s reliability and brand reputation, and where you plan to mount it in your vehicle.

Introducing the Product
The TEKONSHA 90885 / Tekonsha Prodigy P2 Electronic Brake Control is a well-regarded proportional brake controller designed to provide smooth and confident braking for trailers with electric brakes, supporting 1 to 4 axles. Its primary promise is to make towing feel safer and more controlled by automatically applying the trailer brakes with a force that corresponds directly to your tow vehicle’s deceleration. When you purchase the unit, you typically receive the main controller module, a wiring harness (often a universal pigtail, though vehicle-specific harnesses are highly recommended and usually sold separately), and mounting hardware (like metal and plastic brackets). Compared to older time-delay controllers, the Prodigy P2 offers a significant upgrade in braking performance by utilizing an inertia sensor to deliver proportional braking. It’s often considered a benchmark in the aftermarket proportional controller market, sitting comfortably below more advanced units like the Prodigy P3 but well above basic models. This specific electronic brake control is ideal for frequent towers who want reliable, proportional braking and a clear digital display. It might not be the best fit for someone looking for a minimalist, hidden installation, or those who prefer a factory look, as it requires mounting on the dash or console.

* Packaging or included accessories may sometimes arrive damaged or incomplete based on some reports.
Exploring What Makes It Work
The real magic of the Tekonsha Prodigy P2 lies in its core functionalities, which work together to transform the towing experience from stressful to secure. Having used a time-delay controller in the past, the difference the proportional technology makes is night and day.
Proportional Braking Technology – The Heart of the Prodigy P2
This is arguably the most critical feature and the primary reason to choose a proportional brake control over a time-delay unit. The Prodigy P2 uses an internal inertia sensor, similar to an accelerometer, that detects how quickly your tow vehicle is slowing down. As your vehicle decelerates, the controller senses this movement and applies a corresponding amount of braking force to the trailer. This means the trailer’s brakes engage at the same rate as your vehicle’s brakes. The benefit is immediately noticeable: stops are incredibly smooth, controlled, and linear. There’s no jerking sensation as the trailer’s brakes come on late (as with a time-delay), nor do they slam on too hard at the start of the stop. It feels like the trailer is simply stopping right along with you, almost as if it’s not even there. This smooth, coordinated braking significantly reduces wear and tear on both the tow vehicle and the trailer’s braking components and tires, but more importantly, it vastly improves safety by minimizing the risk of jackknifing or losing control during sudden deceleration, especially in adverse conditions.
Clear Digital Display and Intuitive Controls
The Tekonsha Prodigy P2 features a bright, easy-to-read digital LED display. This display is crucial because it provides real-time feedback on what the controller is doing. It shows the amount of braking voltage being sent to the trailer, your gain setting, and important diagnostic codes. Seeing the voltage output helps you understand how much braking force is being applied at any given moment. The controls consist primarily of gain adjustment buttons (plus and minus) and a prominent manual override lever. The gain buttons allow you to easily fine-tune the controller’s sensitivity based on the weight of your load and road conditions. Increasing the gain makes the trailer brakes apply more aggressively, while decreasing it makes them less aggressive. The manual override lever is a vital safety feature, allowing you to quickly apply the trailer brakes independently of your vehicle’s brakes, which can be helpful in controlling trailer sway or during parking maneuvers. The placement and feel of these controls are intuitive, making adjustments and manual braking easy while driving.
Boost Feature for Enhanced Stopping Power
Another useful feature of the electronic brake control is the selectable Boost setting. The Boost feature provides an initial surge of braking power at the very beginning of a stop, before the proportional sensor fully kicks in. This can be particularly helpful when towing heavier loads or when you encounter conditions where you need a bit more assertive trailer braking right from the start, such as on hills or during unexpected quick stops. The Prodigy P2 typically offers multiple Boost levels (often labeled B0, B1, B2, B3) that you can select via the controls. Starting with Boost 0 and adjusting as needed allows you to customize the braking response for different trailers or towing situations, adding another layer of control and confidence.
Simple Installation and Setup
While the universal wiring harness is included, most users benefit greatly from purchasing a vehicle-specific plug-and-play harness (available separately). These harnesses plug directly into a factory port often located under the dash of many modern trucks and SUVs, simplifying the electrical connection significantly. Once the wiring is connected, mounting the unit in an accessible location on the dash or console is straightforward using the provided brackets. A user review highlighted the benefit of using soft plastic dash tools to carefully remove trim panels and drilling small pilot holes before securing the bracket, which are great tips for a clean brake controller installation. After mounting, the initial calibration is incredibly simple: you just need to hook up your trailer and perform a few gentle stops from low speed. The unit self-calibrates its internal sensor during this process. Setting the gain is also easy – you drive at a moderate speed and apply the brakes, then adjust the gain until you feel smooth, firm trailer braking without lock-up. This user-friendly setup process means you can get the system dialed in quickly without needing specialized tools or expertise.
Versatility Across Trailer Types
The Tekonsha Prodigy P2 is designed to work with trailers ranging from 1 to 4 axles. This versatility makes it suitable for a wide variety of towing needs, from single-axle utility trailers to large multi-axle RVs and car haulers. You don’t need a different controller for different trailers within this range, provided they use standard electric brakes. This broad compatibility adds significant value for individuals who tow multiple types of trailers.
Compact Design and Mounting Options
While I mentioned the unit can feel a bit bulky compared to sleek, integrated options, the Prodigy P2 is reasonably compact for a dashboard-mounted controller. It comes with options for mounting brackets, including a metal bracket that provides a very sturdy attachment point. Finding a suitable location on the dash or console requires considering visibility of the display, accessibility of the manual override lever, and clearance around airbags and other vehicle components. The included instructions and user community feedback often provide good guidance on typical mounting spots for various vehicles. A secure and visible mount ensures you can safely monitor the display and access controls while driving.
Built-in Diagnostics and Error Codes
The digital display on the Prodigy P2 is not just for showing voltage and gain; it also displays diagnostic information and error codes. Codes like “ER” typically indicate a trailer disconnect error or a potential wiring issue, while “OL” might signal an overload or short circuit on the trailer’s brake circuit. These diagnostic capabilities are invaluable for troubleshooting trailer wiring problems quickly and alerting you to potentially dangerous situations, such as a faulty connection while driving. Catching these issues early helps prevent damage to the controller or the trailer’s wiring and ensures your brakes are working when you need them most.
