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.

Yes, the T-Connector (part number 118540-037) is designed for the Ford Explorer. Your vehicle must have a Tow-Plug harness located underneath on the passenger's side behind the rear tire with connectors that match the T-Connector harness. If your vehicle does not have this factory Tow-Plug harness, this product will not be compatible.
The T-Connector is a harness that connects to your vehicle's existing Tow-Plug harness to enable trailer towing functionality. It allows you to connect a trailer to your Ford Explorer by tapping into the vehicle's towing electrical system. The harness must be routed along the inside of the bumper toward the center of the vehicle and mounted in an accessible location.
You will need wire cutters and a test-probe. Additionally, you will need a bracket or electrical box (not included with the product) to mount and secure the Trailer Tow Harness in an accessible location after installation.
The vehicle's Tow-Plug harness is located underneath the vehicle on the passenger's side, behind the rear tire. This is where you will connect the T-Connector harness.
First, locate the vehicle's Tow-Plug harness underneath the vehicle on the passenger's side behind the rear tire. Carefully separate the connector without breaking the locking tabs, and ensure all connector surfaces are clean and free of dirt. Then insert the T-Connector harness into the vehicle's Tow-Plug harness and lock it into place.
Route the T-Connector harness along the inside of the bumper toward the center of the vehicle. Be careful to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. After routing, secure all loose wires and mount the Trailer Tow Harness in an accessible location using a bracket or electrical box (not included).
Do not exceed 7.5 amps for stop/turn lights or 7.5 amps for tail lights. You must also not exceed the lower of your towing manufacturer's rating or these limits. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information about your specific towing capacity.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or by connecting a trailer once installed. This ensures all connections are secure and the system is working correctly before towing.
The manual does not specify whether the battery must be disconnected. Consult your vehicle's owner's manual or contact the manufacturer for guidance on electrical safety precautions before beginning installation.
The manual does not mention drilling, cutting, welding, or permanent vehicle modifications. The T-Connector connects to the existing Tow-Plug harness and is routed along the inside of the bumper. However, you will need to obtain a bracket or electrical box (not included) to mount the harness securely.
The manual provides step-by-step installation instructions for a do-it-yourself installation. You will need wire cutters, a test-probe, and a bracket or electrical box to complete the installation. However, the manual does not specify whether professional installation is recommended or required.
The manual confirms that the T-Connector harness is included. A bracket or electrical box for mounting is not included and must be obtained separately. The manual does not provide a complete list of all included components.
