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 3030-037 Electric Trailer Brake Control Wiring Adapter is designed for Mercedes Sprinter vehicles. However, your vehicle must be equipped with an OEM trailer tow package, which includes a green 4-pin connector located under the driver side seat. If your Sprinter does not have this connector, the adapter will not be compatible.
Vehicles not equipped with an OEM trailer tow package will not have the green 4-pin connector. If your Sprinter lacks this connector, the 3030-037 adapter cannot be installed. You should verify with your vehicle's documentation or a Mercedes dealer whether your vehicle includes the OEM trailer tow package before purchasing this adapter.
You will need: a trim panel remover, a Philips screwdriver, and wire cutters.
Removal of the driver side seat may be required to access the green 4-pin connector located under the seat. The manual notes this as a possibility but does not state it is always necessary. You should first attempt to locate and access the connector without removing the seat; if you cannot reach it, seat removal will be needed.
1. Turn off the vehicle and remove the keys from the ignition. 2. Locate the green 4-pin connector under the driver side seat (you may need to remove the seat to access it). 3. Plug the brake control adapter into the vehicle's electric brake control harness connector. 4. Follow all brake control manufacturer's installation instructions for routing and mounting the unit. 5. Perform test procedures as instructed by the brake control manufacturer. 6. Replace all parts removed during installation and ensure all fasteners are reinstalled in their original positions.
Yes. The 3030-037 is a wiring adapter only. You must follow all installation instructions provided by the electric brake control manufacturer, including how to mount the unit, route the adapter to exit the bottom of the dash, and perform test procedures. The adapter simply connects your vehicle's electric brake control harness to the brake control unit.
The maximum amperage rating is 24 amps, which corresponds to a maximum of 4 axles and 8 brakes. However, you must not exceed the lower of either the towing manufacturer's rating (as stated in your vehicle's owner's manual) or this 24 amp specification. Exceeding this limit can cause fires.
Always wear safety glasses during installation. Read and understand all warnings and instructions printed on the tow vehicle's battery before beginning. Follow all warnings and instructions included with the adapter purchase. Do not exceed the amperage ratings stated on the product or in your vehicle's owner's manual, as overloading the circuit can cause fires.
The vehicle must be off with the keys removed from the ignition before you begin installation.
