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 iD Smart Phone Configured Brake Controller for Trailers with 1?4 Axles, Black 90920 (Part #90920 70316) fits 2010-2024 Lexus GX460 models. The 2024 model year is the last year covered by this part number. For newer models, check for an updated version.
The 2010-2024 Lexus GX460 Prodigy iD Smart Phone Configured Brake Controller for Trailers with 1?4 Axles, Black 90920 (Part #90920 70316) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The PRODIGY iD is an electronic brake control system for trailers with 2, 4, 6, or 8 brakes (1–4 axles). It uses an internal inertial sensor to detect vehicle deceleration and proportionally apply brake voltage to the trailer's brakes. The system includes a Dash Module (mounted in the vehicle dashboard), a Power Module (mounted under the hood or in the vehicle), and a Manual Override knob that lets you apply trailer brakes independently at any time. The Tekonsha EDGE™ App is optional but adds additional features.
The PRODIGY iD must be installed in a 12 volt negative ground system. It is not compatible with 24V systems or positive ground vehicles.
The PRODIGY iD can be configured for electric brakes (the most common type) or electric over hydraulic brakes (E/H mode), which are used on some larger trailers and controlled by an electric motor and hydraulic pump. You select the brake type in the menu under Electric/Hydraulic Mode. The manual does not support use with purely hydraulic (non-electric) brake systems.
You will need: drill motor, 7/32" drill bit, 1" hole saw, center punch, 1.5mm Allen/hex wrench, wire cutters, crimp tool, voltage tester, and panel removal tools. If you do not have these tools or need additional assistance, the manual recommends stopping installation and contacting a professional installer.
The kit includes: Power Module, Dash Module, Manual Knob, LED Display, Knob Base, Mounting Collar, Red Cap, Universal Wire Harness, Hardware Kit, and Drill Template. The manual does not specify the contents of the Hardware Kit in detail.
Yes. An automatic reset circuit breaker is required but not supplied with the PRODIGY iD. You must install a 20A circuit breaker for 1–2 axle applications or a 30A circuit breaker for 3–4 axle applications between the BLACK (+) power wire and the positive terminal of the vehicle battery.
The Dash Module should be mounted in the vehicle dashboard at a location where the driver can easily access the Manual Override knob and see the LED display. The mounting location must meet these orientation requirements: the front of the PRODIGY iD must be horizontal (±20 degrees), it can be rotated 0 to 360 degrees in the direction of travel, and it must be parallel to the direction of travel (±20 degrees). The Dash Module can mount in vehicle panels up to 0.17in (5.0mm) thick. Minimum required space behind the dash is approximately 2.32in (59mm) tall, 2.17in (55mm) wide, and 2.68in (68mm) deep. Verify the area behind the dash panel is clear before drilling.
The Power Module can be mounted to any suitable surface using two 14in tie wraps or screws. Do not mount it on or underneath carpeting, as this will prevent proper cooling. The manual does not specify whether the Power Module must be mounted horizontally or vertically, or a specific location such as under the hood or inside the vehicle.
Use the included Drill Template and mark each drill point with a center punch. Drill holes in alphabetical order (A, B, C, D, E) as indicated on the template. Hole sizes are: A, B, D, E = 7/32", and C = 1". The manual emphasizes confirming horizontal center line alignment before drilling to ensure proper display alignment.
1. Insert the Mounting Collar into the drilled hole with the Indicator Arrow pointing up to the 12 o'clock position and the Clamp Wings locked in the inward position. 2. With the Mounting Collar inserted, loosen the screws one-half turn counter-clockwise using the 1.5mm hex key to free the Clamp Wings. 3. Hand-tighten the screws clockwise to clamp the Mounting Collar to the panel. Ensure both Clamp Wings are hand tight. Do not over-tighten, as this can cause improper performance, excessive road noise, and damage to the device.
1. Align the Knob Base with the Indicator Arrow pointing up in the 12 o'clock position. 2. Press straight inward until all three snap fits engage. When properly assembled, the Knob Base should turn evenly with a spring return. 3. Remove the red anti-static cap. 4. Align the large snaps on the Manual Knob with the notches on the Knob Base. 5. Push on until the snaps are fully engaged. 6. Remove the lens protector. Do not touch the electrical contacts after removing the red dust cap, as this may damage the device.
Align the Display Assembly with the logo lettering oriented upwards. Press inward until both snaps are engaged. The display will then be ready to show connectivity and operational status.
The Universal Wire Harness contains four wires: BLACK (Positive Battery, 12VDC), WHITE (Negative Battery, Chassis Ground), RED (cold side of stoplight switch), and BLUE (brake output to trailer). Each wire must be connected to its corresponding function in the vehicle electrical system. Reversing the BLACK and WHITE wires will damage or destroy the brake control.
Connect the BLACK (+) wire through an automatic reset circuit breaker to the positive (+) terminal of the vehicle battery. Use a 20A circuit breaker for 1–2 axle applications or a 30A circuit breaker for 3–4 axle applications. The BLACK wire is the power supply line to the brake control and must be properly fused.
Connect the WHITE wire to a suitable ground location. The negative terminal of the vehicle battery is a suitable ground location in the absence of a Trailer Tow Package connection. Inadequate grounding may cause intermittent braking or insufficient voltage to trailer brakes and may result in accidents.
Connect the RED (stop light) wire to the vehicle's braking circuit on the cold side of the stoplight switch (voltage only when the brake pedal is pushed). Do not disrupt the vehicle's braking circuit. If you are unsure which wire to use, contact your local vehicle dealer, Tekonsha dealer, or technical support.
Connect the BLUE (brake output) wire to the trailer connector's brake wire. This wire carries the proportional brake signal from the PRODIGY iD to the trailer's electric brakes.
Use proper gauge wire when installing the brake control; smaller gauge wire may result in less efficient braking. Minimum wire gauges are: 14 AWG for 1–2 axle applications, and 12 AWG for 3–4 axle applications. Soldering is recommended, or crimp-on butt connectors are a suitable substitution.
Yes. If your vehicle comes equipped with a factory tow package, brake control function wires with a connector may exist under the vehicle dash. A vehicle-specific Plug & Play harness may be purchased separately. To install, simply plug the vehicle-specific connector into the factory tow package harness and plug the other end directly into the Plug & Play Harness on the brake control. Consult your vehicle manual or call Tekonsha for the location of the factory harness.
Route all wires as far from the radio antenna as possible to reduce AM interference. Additionally, do not mount or activate RF generating items (such as two-way radios) near (less than 12in to) the Dash Module or Power Module.
The Gross Combined Weight Rating (GCWR) is the maximum combined weight of the tow vehicle and trailer as specified by the vehicle manufacturer. The GCWR must never exceed the vehicle manufacturer's recommendation. Exceeding the GCWR can result in accidents and unsafe towing conditions.
Proportional braking is the default operating mode of the PRODIGY iD. It uses an internal inertial sensor to detect the deceleration rate of the tow vehicle and trailer, then generates a brake output voltage proportional to that deceleration. This means the trailer brakes are applied in proportion to how hard the tow vehicle is braking, providing smooth and coordinated braking. The PRODIGY iD will also brake proportionally in reverse, applying appropriate brake voltage based on deceleration.
The Manual Override is the rotary control knob on the Dash Module. It allows you to apply the trailer brakes to the maximum power set by the Power Output setting, independent of vehicle braking. When you rotate the Manual Override clockwise, the Brake Output Voltage will increase from zero and go to the maximum value as set by the Power Control setting. This lets you apply trailer brakes at any time, such as when descending a long hill or during parking.
The Boost feature allows more aggressive braking by increasing the sensitivity of the PRODIGY iD's inertial sensor, enhancing trailer brake participation during a braking event. Boost has four levels: OFF, Level-1, Level-2, and Level-3. Select your Boost setting based on your towing situation, driving preference, and condition of your trailer brakes. Do not use Boost during icy road conditions. Boost is disabled in Timer mode. Never use Boost to compensate for a potential problem with your trailer brakes; have your trailer brakes adjusted or repaired immediately.
Reverse Mode allows you to temporarily cancel the effects of Boost, which can be useful during parking, especially when backing up the trailer. Reverse Mode lasts for 3 minutes or until you select the Reverse Clear option from the menu. You are notified that Reverse Mode is in effect by the display showing a specific indicator. Access Reverse Mode through the Programming Menu or the EDGE™ App.
Always warm your trailer brakes before setting the Power Output. To warm the brakes, drive a short distance of ¼ mile (0.4 km) at about 45 mph (70 kph), applying the Manual Override at a low setting to allow the trailer brakes to engage at a low level. Warm trailer brakes tend to be more responsive than cold brakes. After warming, set the Power Output on a dry, level paved surface at 25 mph (40 kph) by fully applying the Manual Override and adjusting until the brakes are just below wheel lock-up or at a force sufficient for maximum braking power.
If the Power Output is set too high, the trailer brakes will lock up, causing the trailer wheels to skid. Skidding trailer wheels can cause loss of directional stability of both the trailer and tow vehicle, which is dangerous. The power should never be set high enough to cause trailer brakes to lock up. If trailer brakes lock up during testing, decrease the Power Output.
The PRODIGY iD will HOLD your trailer with 25% of the power setting while you are at a standstill with the brake pedal applied for longer than 5–7 seconds. This feature helps prevent trailer creep on hills or in traffic.
After installation, rotate the Manual Override to verify that the Dash Module and Display are illuminated. The display will flash a specific indicator if the trailer is not connected, or a different indicator when the trailer is connected. Once the PRODIGY iD Dash Module and Display Assembly have been installed correctly and power is applied, the display will indicate connectivity. If the display shows a flashing trailer disconnected indicator for 15 seconds then changes to a dot, check all connections to the trailer.
If the display is blank, the PRODIGY iD may be in Power Saving Mode (which occurs after 15 minutes of no motion or braking activity), or there may be a loss of connection or power. Try depressing the brake pedal or Manual Override to wake the unit. If the display remains blank, verify the connection from the Power Module to the Dash Module, verify the connection to the Power Module and vehicle, verify battery voltage on the black wire (should be 12–14 volts), and verify ground on the white wire. If vehicle battery input exceeds 17.0V, this can also cause a blank display.
Trailer brakes must be adjusted after the first 200 miles (320 km) of operation, and then at 3,000 mile (4,800 km) intervals, or as use and performance requires. Proper brake adjustment ensures optimal braking performance and safety.
1. Jack up the trailer and secure it on adequate capacity jack stands, following the trailer manufacturer's recommendations. Never lift or support the trailer on any part of the axle or suspension system. 2. Check that the wheel and drum rotate freely. 3. Remove the adjusting hole cover from the adjusting slot on the bottom of the brake backing plate. 4. With a screwdriver or standard adjusting tool, rotate the star wheel of the adjuster assembly to expand the brake shoes until the wheel is very difficult to turn. 5. Rotate the star wheel in the opposite direction until the wheel turns freely with a slight lining drag. 6. Replace the adjusting hole cover and lower the wheel to the ground. 7. Repeat on all brakes. For drop spindle axles, use a modified adjusting tool with about an 80 degree angle.
This indicates the trailer is disconnected from the tow vehicle, or there is a problem with the trailer connector or wiring. Check and clean the trailer and tow vehicle connectors; they may be dirty, corroded, or have bent/misaligned terminals. Verify that the trailer or tow vehicle connector is wired correctly. Check for an open on the electric brake wire (broken or disconnected wire) or loss of ground to the brake magnets (broken or disconnected wire). Repair or replace wiring as needed.
An open ground indicator (flashing 2 times per second) means the Power Module has lost connection to the vehicle battery ground while the trailer is connected. Check the connection to ground on the white wire of the Power Module. Verify that the white wire is securely connected to a suitable ground location, such as the negative terminal of the battery.
An electrical overload indicator (flashing 2 times per second) can indicate a defective brake magnet, an intermittent short on the electric brake wire or bare wire, or that the total brake current exceeds the 4-axle load capacity. It can also indicate thermal overload, which reduces braking power. Locate and replace any defective brake magnets, locate and repair faulty brake wires, decrease the electrical load, or allow the system to cool if thermal overload is the cause.
A short circuit indicator (flashing 2 times per second) means the Power Module detects a brake wire short to ground. This can be caused by use of some test lights or non-Tekonsha testers, a short in the 7-way connector between brake output and other terminals, or an electric brake wire on the tow vehicle or trailer that is shorted out. Use only Tekonsha-approved test lights or testers. Inspect and repair the trailer connector if needed. Inspect and repair or replace the electric brake wire.
A power interruption indicator (flashing for 15 seconds) means the Manual Override or brake pedal was applied while connecting to power, or was activated within 5 seconds of initial power being applied to the Power Module. It can also indicate a poor connection to battery power or reversed red and black wires. Unplug the Power Module from the vehicle, verify that the Manual Override or brake pedal is not applied for 10 seconds after reconnecting to power, verify the connection to battery power, and verify that the red and black wires are connected correctly.
If the display flashes continuously and there is no braking, the Power Control may be set to zero. Increase the Power Setting through the Programming Menu. If braking is still not sufficient, increase the Power Output further. If the problem persists, check all wiring connections and verify that the trailer is properly connected.
A communication error (flashing for 15 seconds) indicates a communication failure between the Power Module and Dash Module. The controller type may have defaulted to Timer mode, and the display may be blank or show partial or complete loss of Manual Override braking. Check the Dash Module harness for connection and/or damage. Verify that the 4-pin Universal Wire Harness is properly connected between the Power Module and Dash Module.
If the display shows an internal error (flashing continuously), there is an internal problem with the PRODIGY iD. Contact Tekonsha Technical Support at 1-800-632-3290 or www.tekonsha.com for assistance.
The PRODIGY iD works with 12 volt negative ground vehicles and trailers with 2, 4, 6, or 8 electric or electric over hydraulic brakes (1–4 axles). It requires a minimum of 2.32in (59mm) tall × 2.17in (55mm) wide × 2.68in (68mm) deep space behind the dashboard. The manual does not list specific vehicle makes or models; contact Tekonsha at 1-800-632-3290 to confirm fitment for your vehicle.
You must purchase an automatic reset circuit breaker (20A for 1–2 axles, 30A for 3–4 axles). Depending on your vehicle, you may also need to purchase a vehicle-specific Plug & Play harness if your vehicle has a factory tow package. All other components are included in the kit.
Yes. You must drill four 7/32" holes and one 1" hole in the dashboard panel to mount the Dash Module. Use the included Drill Template to mark the holes. Ensure the area behind the dashboard is clear before drilling.
Use 14 AWG wire for 1–2 axle applications and 12 AWG wire for 3–4 axle applications. Smaller gauge wire may result in less efficient braking.
Set the Power Output just below the point where trailer brakes lock up, or at a force sufficient for maximum braking power. Never set power high enough to cause trailer brakes to lock up, as this can cause loss of directional stability. Always warm trailer brakes first by driving ¼ mile at 45 mph with the Manual Override at a low setting.
No. Do not use the Tekonsha EDGE™ App while driving. The app is optional and adds additional features, but should only be used when the vehicle is parked.
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.
The manual does not specify whether the battery must be disconnected. Consult the brake control manufacturer's installation instructions, which you must follow as part of the complete installation process.
First, plug the brake control adapter into the mating receptacle on the backside of the brake control unit. Then attach the adapter to the vehicle's 5-pin electric brake control harness connector. This sequence prevents accidental connection to the wrong connector.
Locate a suitable grounding point near the brake control harness connector, such as an existing ground stud. If no suitable point exists, drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Clean dirt and rustproofing from the area before securing. Do not drill into the vehicle floor or bed.
Drilling is required only if no suitable existing ground stud is available near the brake control harness connector. If drilling is necessary, drill a 3/32" hole for the white ground wire. Do not drill into the vehicle floor or bed. Clean the area of dirt and rustproofing before drilling.
The adapter supports a maximum of 4 axles with 8 brakes (24 amps). Do not exceed the lower of your towing manufacturer's rating or this limit. Exceeding this capacity can cause circuit overload and fire risk.
Wear safety glasses during installation. Read and follow all vehicle warnings and installation instructions before beginning. Follow all brake control manufacturer's installation instructions and perform test procedures as instructed. Do not drill into the vehicle floor or bed. Do not exceed the maximum brake capacity (4 axles, 8 brakes, 24 amps) to prevent fire risk.
