The Tekonsha Brakeman IV digital trailer brake controller provides safety and connection when you need it most. As a time-based controller, the Brakeman IV is a great choice for basic, light-duty towing needs. This compact controller 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. The Brakeman IV has up-front buttons so you can easily adjust power output, the sync ? or aggressiveness with which the controller applies the brakes, and engage manual override to help you brake safely when an unexpected stop pops up. It also works with electric or electric over hydraulic braking systems, and features advanced internal circuit protection, real time comprehensive diagnostics, and short circuit protection. Because the Brakeman IV is a time-based controller, there?s no requirement that it be positioned in the direction of travel; it can be installed anywhere you like as long as it is within reach of the driver. Plus, the Plug & Play feature allows for quick and easy connection with your vehicle?s wiring. The Brakeman IV trailer brake controller works with1-4 axle trailers, comes with all the mounting hardware needed for installation, and is backed by a limited lifetime warranty.

Reese Towpower delivers the towing hardware most drivers reach for: receiver hitches across multiple classes, ball mounts, hitch balls, pins, clips, safety chains, wiring and hitch accessories. Backed by a towing pedigree dating to 1952, the line uses all-welded construction and corrosion-resistant finishes, with custom-fit hitches matched to vehicle make, model and year.
The Reese story starts in 1952, when Margaret Reese challenged her husband TJ to do something about travel trailers rocking whenever anyone walked through them. A few years later he built the first pair of stabilising jacks. The idea was simple and it worked, and it changed how the RV industry thought about trailer stability. From that beginning the Reese name grew into a full towing line covering fifth wheel hitches, pin boxes, weight distribution systems and accessories, and Reese Towpower carries that engineering into the products most owners buy off the shelf.
Receiver trailer hitches anchor the range, offered across the classes needed for everything from a small utility trailer to livestock and job-site loads. Construction is all-welded rather than bolted at the stress points, and each hitch is tested against published standards for strength and safety. Custom-fit hitches are engineered to the vehicle manufacturer's weight specifications for a given model and model year, so mounting points line up with existing frame holes and the finished installation sits where it should. Exclusive paint finishes resist rust and corrosion through years of road salt, and hitches carry a nationwide limited lifetime warranty.
No towing setup is complete without the connecting hardware, and Reese Towpower covers it comprehensively. Ball mounts come in fixed, adjustable and specialty forms with a range of rises and drops to level a trailer properly. Hitch balls are offered in the standard diameters and shank sizes, matched to coupler and load rating.
The towing accessories line fills in everything else: hitch pins and clips, locks, receiver tube covers, and safety chains rated to the load being pulled. For most drivers this is where a towing purchase actually begins, and having the whole chain of components from one engineering source keeps ratings consistent end to end.

The 2015-2017 Toyota Tundra Reese Towpower Brakeman IV Time Delay Brake Controller for Trailers with 1 to 4 Axles Black 8507111 (Part #8507111 70246) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the 3031-037 is designed for Toyota Tundra. The installation accesses the center dash panel on the driver's side and connects to the vehicle's electric brake control harness.
Yes, the 3031-037 is designed for Toyota Tacoma. The installation accesses the electric brake control harness located underneath and to the left of the steering column, behind the kick panel.
The adapter can be installed, but vehicles not equipped with an OEM trailer tow package may require additional fuses and relays to complete the output and battery feed circuits. These are sold separately. Consult your vehicle's owner's manual for fuse and relay locations.
A trim panel remover is required for Tundra installation. For Tacoma, the harness is accessed behind the kick panel without requiring a trim panel remover tool.
The manual requires that the vehicle be off with keys removed from the ignition before beginning installation. The manual does not specify whether the battery must be disconnected.
Locate the access panel in the center of the dash on the driver's side. Using a trim panel puller, locate the notch in the panel and pry it out and away from the dash carefully to avoid damage. Unplug the housings attaching the panel, being careful not to damage the locking tabs, and set aside.
Locate the vehicle's electric brake control harness underneath and to the left of the steering column, behind the kick panel. It will be taped to another harness near the emergency brake pedal. You will find a white 10-pin connector that mates with the adapter connector.
The white housing contains male terminals and is the mating connector for the vehicle's brake control harness. For Tundra, carefully pull the housing towards the access panel and plug in the mating white housing from the brake control adapter. For Tacoma, carefully remove tape and plug the mating white housing from the adapter into the vehicle's electric brake control harness connector.
You should first locate a suitable grounding point near the connector, such as an existing ground stud. If no existing ground point is available, you may drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Do not drill into the vehicle floor or bed. Clean dirt and rustproofing from the area before securing the ground wire.
Locate a routing path for the adapter to exit the bottom of the dash. Use a flashlight to shine light up through the bottom of the dash to locate a hole to exit the dash.
After the brake controller is installed, plug in all connectors that were not used back into the original housings and snap the access panel back into place.
The adapter housing contains four male terminals: #5 is Ground, #7 is Trailer Brake, #8 is Fuse Trailer Brake Controller, and #9 is Vehicle Stop Lamp.
The maximum rating is 18 amps for a configuration of 3 axles with 6 brakes. Do not exceed the lower of your towing manufacturer's rating or this 18 amp specification. Overloading the circuit can cause fires.
Always wear safety glasses during installation. Always read and follow all warnings and instructions included with the product before beginning installation. Always read, understand and follow all warnings and instructions printed on the tow vehicle's battery. Always read your vehicle's owner's manual and the brake control instruction sheet for additional information.
Yes. After the adapter is installed, you must complete the installation per the electric brake control manufacturer's instructions and mount the unit as directed. You must also perform test procedures as instructed by the brake control manufacturer.
