The Tekonsha Prodigy P3 electric trailer brake controller is the epitome of excellence when it comes to trailer braking. As one of the most asked for units on the market, this proportional brake controller utilizes primary sensor technology to provide a smooth braking response in any stopping situation. With up-front push-button controls and a distinct, tri-lingual, multi-color LCD display, this intelligent brake controller makes it easy to adjust trailer braking preferences and monitor braking activity. The Prodigy P3 shares many of the same great features as the Prodigy P2, including a power output button to quickly and easily set your desired braking power, a boost option that lets you apply up to three levels of additional trailer braking power, especially when hauling heavier loads, and manual override. You can also choose between electric or electric over hydraulic braking, and more, with just the push of a button! What sets the P3 apart is its storage. With this unit, you have the ability to create and store up to five trailer settings and/or driver preferences and easily adjust them as needed. This compact, dash-hugging proportional brake control has everything you need to stop safely when on the road. When you?re done towing, the P3?s snap-in dash mounting clip, Plug & Play port for two plug adapters, and removeable electrical connector allow the unit to be quickly stored. The Prodigy P3 works with trailers with 1-4 axles, comes with all the mounting hardware needed for installation, and is backed by a limited lifetime warranty.

Tekonsha is a leading manufacturer of electronic trailer brake controllers, pioneering the category in the 1970s. The lineup spans proportional units such as the Prodigy P3 and Prodigy iD, time-delayed controllers, the wireless Prodigy RF, plus vehicle-specific wiring harnesses, adapters and trailer brake components engineered for smooth, predictable stopping at any speed.
Tekonsha Engineering Company began in 1964 building RV steps and mirrors. Within a few years it had found its real calling, and by the 1970s Tekonsha was pioneering the manufacture of electronic trailer brake controllers, the product category that still defines the brand. More than half a century later it remains the reference name in trailer braking and is part of the Horizon Global group alongside Reese, Draw-Tite, Fulton, Bulldog and Wesbar.
A brake controller is the component that tells a trailer's electric brakes how hard to work and when, and getting that right is the difference between a controlled stop and a shove from behind. Tekonsha builds both major types. Proportional controllers use an internal accelerometer to sense how quickly the tow vehicle is slowing and apply trailer braking to match, so light braking stays light and hard braking is immediate. Time-delayed controllers ramp to a preset output over a fixed interval, a simpler and more economical approach that suits occasional towing.
The current brake controller range covers most of that ground. The Prodigy iD pairs with a phone through Tekonsha's EDGE technology for setup and monitoring, the P3 offers storable settings for multiple trailers and a trilingual colour LED display, the Prodigy P2 adds a dimmable display and boost mode for heavier loads, and the Voyager keeps operation simple and dependable. The Prodigy RF mounts to the trailer itself and controls wirelessly, which suits rental fleets and drivers who swap tow vehicles.
Installation is supported by vehicle-specific brake control harnesses that plug into a factory connector rather than requiring cut-and-splice wiring, along with mounting brackets and adapters. Matched controller bundles pair a unit with the correct harness. Products are tested to meet and often exceed published industry standards.

The 2010-2024 Lexus GX460 Prodigy P3 Proportional Brake Controller for Trailers with 1?4 Axles, Black 90195 (Part #90195 70316) fits the following vehicles: 2010-2024 Lexus GX460. Always verify your specific year, make, and model before ordering.
Yes, the 2010-2024 Lexus GX460 Prodigy P3 Proportional Brake Controller for Trailers with 1?4 Axles, Black 90195 (Part #90195 70316) is designed to fit the 2010-2024 Lexus GX460.
The 2010-2024 Lexus GX460 Prodigy P3 Proportional Brake Controller for Trailers with 1?4 Axles, Black 90195 (Part #90195 70316) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The P3 is an electronic brake control for trailers with 2, 4, 6, or 8 brake applications. It uses an inertial sensor to detect deceleration and proportionally apply power to trailer brakes based on how hard the tow vehicle is braking. It also features a Hold function (25% power at standstill for over 5 seconds) and Boost settings (B1, B2, B3) for more aggressive braking.
The P3 can be configured for either electric or hydraulic brakes. You must select the brake type during setup by pressing Menu/Options, selecting Brake Type, and choosing Electric or Hydraulic.
The P3 includes a pigtail wiring harness and mounting hardware: #8 x 3/8" machine screws with internal tooth washers for traditional bracket mount, or #8 x 3/8" self-tapping screws for under-dash pocket mount. Do not use longer screws as they may damage the unit.
The manual does not specify whether drilling is required. It provides two mounting options (traditional bracket mount and under-dash pocket mount) but does not detail the preparation of the mounting surface. Consult the specific mounting location requirements or contact Tekonsha at 1-888-785-5832.
Yes. If your vehicle came with a factory tow package that included a 7-way connector, you can purchase a Tekonsha OEM-specific wiring harness with the P3 connector on one end and your vehicle's connector on the other.
The P3 power output range is 0.0 to 15 volts. You set the power level using the Power Buttons, and the display shows the current voltage output to the trailer brakes.
The Hold function automatically applies 25% of the power setting to hold the trailer in place while you are at a standstill with the brake pedal applied for longer than 5 seconds. It releases when you release the brake pedal.
Boost is a feature with three levels (B1, B2, B3) that increases the sensitivity of the inertial sensor for more aggressive trailer braking. B1 starts at approximately 13% power; B2 and B3 start at approximately 25% power. Use Boost when you want trailer brakes to lead the tow vehicle's braking, when towing a full vs. empty trailer, or if trailer brakes are worn. Boost is not intended for icy road conditions.
1. Connect trailer to tow vehicle with engine running and set power to 6.0 using Power Buttons. 2. Drive on a dry level paved surface at 25 mph and fully apply the Manual Knob. 3. If brakes lock up, turn power down; if braking is insufficient, turn power up. 4. Repeat until power is set just below wheel lockup or at maximum braking force. 5. Test with low-speed brake pedal stops to verify the setting. Always warm trailer brakes first by driving 1/4 mile at 45 mph with manual lever engaged at low level.
Proportional braking means the P3 uses an inertial sensor to detect how hard the tow vehicle is decelerating and automatically applies proportional power to the trailer brakes. The harder you brake, the more power is sent to the trailer brakes. This creates a unified braking feel between the tow vehicle and trailer.
Yes. The P3 will apply the appropriate brake voltage based on deceleration when backing a trailer, providing proportional braking in reverse.
Yes. Press and hold the Boost button continuously for 5 seconds with the brake pedal depressed. The display will show an "R" arrow icon flashing. Boost and Hold will automatically return to your previous settings after 3 minutes, or you can press the Boost button again to restore them sooner.
The P3 can be mounted from 0 to 360 degrees vertically in the direction of travel. However, the front of the P3 must be horizontal and the unit must be parallel to the direction of travel. The P3 will automatically acquire and maintain the proper level setting and will automatically adjust as you travel up or down hills.
Yes. Do not mount or activate RF-generating items such as cell phones or two-way radios within 12 inches of the brake control, as they can interfere with the P3's operation.
Two mounting options are provided: (1) Traditional Bracket Mount using a mounting bracket and #8 x 3/8" machine screws with internal tooth washers, or (2) Under Dash Pocket Mount using a T Slot Mount, small metal bracket, and #8 x 3/8" self-tapping screws. Both require mounting to a solid surface. Do not use longer screws as they may damage the unit.
After successful wiring, you should see: (1) Power to P3 without trailer connected; (2) Power to P3 with trailer connected and Boost engaged (B1); (3) Manual Knob activated without trailer; (4) Manual knob activated with trailer showing voltage output (e.g., 5.4 volts, range 0.0 to 15 volts); (5) Power saving mode if no motion or activity for 15+ minutes.
Press the Menu/Options Button to view the Setup screen. Select/highlight Brake Type and press OK. Select/highlight Electric or Hydraulic and press OK. Select/highlight Confirm and press OK. The screen will display the Brake Type Setting (E for Electric or H for Hydraulic) in the lower left corner.
The manual provides a chart with recommended Boost settings based on trailer weight compared to vehicle weight (with properly adjusted trailer brakes): Trailer weighs less than vehicle: Boost OFF or B1; Trailer weighs approximately same as vehicle: Boost OFF, B1, or B2; Trailer weighs up to 25% more: B1, B2, or B3; Trailer weighs up to 40% more: B2 or B3; Trailer weighs over 40% more: B3. Select based on your towing situation, driving preference, and trailer brake condition.
The P3 troubleshooting menu displays voltage and current information by wire color: Black wire = vehicle battery voltage; Red wire = voltage from stoplight switch with brake pedal depressed; Blue wire = average voltage provided to trailer brakes and current provided to trailer brakes.
GCWR (Gross Combined Weight Rating) is the maximum combined weight of the tow vehicle and trailer as specified by the vehicle manufacturer. The P3 manual warns that GCWR must never exceed the vehicle manufacturer's recommendation. Exceeding GCWR can compromise vehicle control and safety.
Warm trailer brakes tend to be more responsive than cold brakes. To warm trailer brakes before setting power, drive a short distance (1/4 mile) at 45 mph with the manual lever engaged enough to cause trailer braking at a low level. This ensures accurate power calibration.
If power is set too high, trailer brakes may lock up and the wheels may skid. Skidding trailer wheels can cause loss of directional stability of both the trailer and tow vehicle. Power should never be set high enough to cause trailer brake lockup; instead, set it just below wheel lockup or at a sufficient force to achieve maximum braking power.
When power is set correctly, you should feel unified braking between the trailer and tow vehicle. The trailer should brake proportionally with the tow vehicle without locking up or providing insufficient braking force.
Trailer brakes should be adjusted after the first 200 miles of operation (when brake shoes and drums have seated) and at 3,000-mile intervals, or as use and performance requires. Increased Boost settings may be needed if trailer brakes are worn; refer to Appendix A or a dealer for brake adjustment or repair.
1. Jack up trailer on adequate capacity jack stands (follow trailer manufacturer recommendations; do not lift on axle or suspension). 2. Remove adjusting hole cover from the adjusting slot on the bottom of the brake backing plate. 3. With a screwdriver or standard adjusting tool, rotate the starwheel to expand brake shoes until the wheel is very difficult to turn. 4. Rotate the starwheel in the opposite direction until the wheel turns freely with slight lining drag. 5. Replace the adjusting hole cover and lower the wheel. 6. Repeat on all brakes. For drop spindle axles, use a modified adjusting tool with approximately 80-degree angle.
Yes. Press Menu/Options to view Setup screen, select Help, then Display. You can adjust: Brightness (High/Normal/Low), Color (Pink/White/Blue/Light Blue/Cyan/Green/Light Green/Orange/Magenta), and Contrast (Normal/High). High contrast displays text in black on a colored background.
Yes. The P3 allows you to store up to 5 different trailer presets. Press and hold the Boost button for 2 seconds until the Select menu appears. Arrow down to select the preferred Trailer setting and press OK. You can then customize Brake Type, Power Setting, Boost Setting, Language, and Brightness/Color/Contrast for each preset.
The P3 supports English, French, and Spanish. To change language, press Menu/Options, select Help, then Language, and choose your preferred language.
This warning indicates that the trailer is connected but the P3 has lost its connection to the battery ground. Check that the ground wire (black wire) is securely connected to a clean, solid ground point on the tow vehicle.
This warning indicates that the P3 detects an excessive current overload condition during operation. This may indicate a short circuit or fault in the trailer brake wiring or brakes. Check all wiring connections and consult a dealer if the problem persists.
This warning indicates either (1) the brake output wire is shorted to ground during idle condition, or (2) a test light or non-Tekonsha tester is being used and causing the warning. Check that the brake output wire (blue wire) is not damaged or touching ground. If using a test light, use only Tekonsha testers to avoid false warnings.
This warning indicates that power to the P3 was interrupted during braking, or the stop lamp was active while connecting power to the trailer brake control. Ensure the power connection (red wire) is secure and that you do not connect power while the brake pedal is depressed or the stop lamp is active.
This warning indicates one of four possible issues: (1) Trailer is not connected to the tow vehicle; (2) Trailer is connected but there is an open circuit on the brake line; (3) Trailer connector is disconnected or corroded; (4) Loss of trailer brake magnet ground. Check the trailer connection, inspect the brake line for breaks, clean corroded connectors, and verify the brake magnet ground is secure.
Press Menu/Options to view Setup screen. Select Help and press OK. Select Trouble Shoot and press OK. The menu displays four diagnostic functions: vehicle battery voltage (black wire), stoplight switch voltage with brake pedal depressed (red wire), average voltage to trailer brakes (blue wire), and current to trailer brakes (blue wire).
First, verify the trailer is properly connected and the brake type (Electric or Hydraulic) is correctly set. Use the troubleshooting menu to check: (1) vehicle battery voltage (black wire) should be present; (2) stoplight switch voltage (red wire) should show when brake pedal is depressed; (3) voltage to trailer brakes (blue wire) should increase when braking. If voltage is present but brakes do not respond, the trailer brakes may need adjustment or repair (see Appendix A or consult a dealer).
The 18285-037 is a wiring adapter that connects an electric trailer brake control to a vehicle's factory electric brake control harness. It allows you to plug a brake control unit into your vehicle's existing 5-pin brake control connector without modification to the vehicle's original wiring.
No. The adapter is designed for vehicles that have an electric brake control harness with a 5-pin connector located underneath and to the left of the steering column, taped to another harness near the emergency brake pedal. Check your vehicle for this harness before purchasing.
The harness is located underneath and to the left of the steering column. It will be taped to another harness near the emergency brake pedal. Look for a 5-pin connector on this harness that matches the one on the adapter.
The adapter includes an eyelet and screw for securing the white ground wire. These are used to attach the ground wire to a grounding point near the brake control harness connector.
