The Pro Series Pilot trailer brake controller is a great option for those who tow light loads at all hours of the day and night, in all types of weather. Its dark, smokey lens makes it ideal for direct light applications, creating optimum visibility to read the large, two-digit display. The Pilot brake controller kit is a time-based controller that works by electronically connecting your vehicle and your trailer. When you hit the brakes in your tow vehicle, it generates an output signal that ramps up, or increases over a period of time, applying braking power to your trailer at a fixed rate. Its large, easy-to-read dual digit display shows power output and the aggressiveness with which the controller applies the brakes. The Pilot also has manual override to help you brake safely when an unexpected stop pops up. It features advanced internal circuit protection, real time diagnostics, short circuit protection, and loss of ground. Because the Pilot is time-based, it can be mounted in any direction. Plus, the Plug & Play feature allows for quick and easy connection with your vehicle’s wiring. The Pilot trailer brake controller works with 1-3 axle trailers, comes with all the mounting hardware needed for installation, and is backed by a limited 1-year 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 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.
After installation, you must perform test procedures as instructed by the brake control manufacturer. The manual requires that you complete the installation per the electric brake control manufacturer's instructions and mount the unit as directed before testing.
The adapter fits vehicles with a 5-pin electric brake control harness located under the steering column, left side, near the emergency brake pedal. Check your vehicle for this connector before purchasing.
Drilling is only required if no existing ground stud is available. If needed, drill a 3/32" hole for the white ground wire. Do not drill into the vehicle floor or bed.
Maximum 4 axles with 8 brakes (24 amps). Do not exceed the lower of your towing manufacturer's rating or this limit to prevent fire risk.
Plug the adapter into the brake control unit first, then connect it to the vehicle's 5-pin harness connector. Ground the white wire to an existing stud or a 3/32" drilled hole.
The adapter includes an eyelet and screw for grounding the white wire to a suitable point near the brake control harness connector.
