The Tekonsha Prodigy P3 is a proportional trailer brake controller built for drivers who want adjustable braking and a clear diagnostic display. It can control electric or electric-over-hydraulic trailer brakes on as many as eight wheels, but vehicle and trailer compatibility must be confirmed before purchase.

| Controller type | Proportional |
|---|---|
| Trailer brake systems | Electric and electric-over-hydraulic |
| Axle/wheel capacity | Up to 4 axles / 8 braked wheels |
| Electrical rating | 30 amps |
| Mounting | Self-leveling design; follow Tekonsha orientation instructions |
| Warranty | Limited lifetime |
Why proportional control matters
A proportional controller senses tow-vehicle deceleration and commands trailer braking to match. When properly adjusted, that can feel more natural than a time-based controller that increases output according to a preset schedule. It does not remove the need for setup: trailer weight, road conditions and brake adjustment all influence the gain and boost setting you need.
The P3’s display provides output information and diagnostic messages. That is helpful when identifying connection faults or confirming what the controller is doing, but it is not a substitute for inspecting plugs, wiring, grounds, magnets and mechanical brake condition.
Compatibility comes first
Part number 90195 identifies the controller. The wiring harness may be a separate vehicle-specific purchase. Some trucks have a factory connector that accepts a plug-in harness; others require a more involved installation. Modern vehicles may also include an integrated factory brake controller, making an aftermarket unit unnecessary or complicating the decision.
- Confirm the trailer uses compatible electric or electric-over-hydraulic brakes.
- Check the tow vehicle owner’s manual and Tekonsha fit information.
- Identify the correct vehicle-specific harness or installation method.
- Choose a mounting location the driver can reach for manual activation.
- Set gain and boost in a safe test area according to the manuals.
Who should choose it
The P3 makes sense for people towing a travel trailer, equipment trailer or car hauler with a compatible braking system, especially when the tow vehicle lacks a capable integrated controller. Drivers who change trailers may appreciate the adjustable boost and visible diagnostics.
If you strongly prefer a clean dashboard, compare under-dash or app-assisted systems—but weigh convenience against the need to reach the manual control quickly. If your vehicle already has an integrated unit, start with the vehicle manufacturer’s guidance before replacing or bypassing it.
Safety notes
A brake controller is only one part of the system. Correct hitch setup, tire condition, breakaway switch operation, trailer brake maintenance, load distribution and legal compliance still matter. After installation, test at low speed away from traffic. Recheck settings when load or road conditions change.
Our buying take
The Prodigy P3’s appeal is control and transparency. It gives a careful owner tools to tune trailer braking and see diagnostic information without relying on a phone. Buy the controller only after confirming the installation path and harness; those details determine whether it is a straightforward upgrade or a wiring project.
