Blue Ox is known internationally for recreational and commercial towing products, manufacturing in Pender, Nebraska since 1925. The line covers tow bars and vehicle-specific baseplates for flat towing behind a motorhome, sway control and weight distributing hitches, supplemental braking accessories and towing wiring, backed by patented designs and long-standing customer service.
Blue Ox has manufactured since 1925 and is recognised internationally for towing products and customer service. The company operates from Pender, Nebraska, where it grew out of Automatic Manufacturing Co., a business that started with cattle oilers and developed into agricultural equipment, tractor accessories and trailer towing hardware. That agricultural engineering heritage still shows in how the towing products are built, and the company holds patents across weight distribution, fifth wheel and tow bar designs.
Flat towing is the discipline Blue Ox is best known for. Towing a car with all four wheels on the ground behind a motorhome demands a system that stays rigid under braking, articulates properly over uneven ground, and connects to the towed vehicle at points strong enough to take the load. Blue Ox tow bars handle the first two, with self-aligning arms that latch under tension and release without a struggle when the load is off them. Vehicle-specific baseplates handle the third, engineered per make and model to tie into structural mounting points behind the fascia.
The wider flat towing range covers supplemental braking systems, safety cables and the accessories that make a complete legal setup, along with baseplate wiring and dinghy towing harnesses that pass lighting signals to the towed vehicle without back-feeding its electrical system.
For conventional trailer towing, Blue Ox weight distributing hitches with integrated sway control transfer tongue load onto the tow vehicle's front axle and resist the yaw that crosswinds and passing trucks induce.
The company describes its foundation as customer service, designing around what owners actually ask for, and it runs an RV park adjacent to the factory where customers can stay. Sister operations at the same Nebraska site include Automatic grain roller mills and MAD-RAMPS pivoting ramp systems.

Zip ties are needed to secure the wiring harness throughout the vehicle. The manual does not specify whether additional tools such as a socket set, wire strippers, or crimpers are required.
The kit includes a converter box, wiring harness with yellow and green leads, a 4-way flat harness, double-stick tape for mounting the converter box, a white grounding wire with ring terminal, a screw for the grounding connection, and zip ties.

The manual does not specify whether battery disconnection is required. Contact Blue Ox customer service at (402) 385-3051 for guidance on this safety step before beginning installation.
Remove the fasteners holding the tail light housings in place on both the driver and passenger side. Carefully pull the housings away from the vehicle, being careful not to break the alignment tabs or housing. Keep the fasteners for reinstallation.
Mount the converter box on the driver side behind the tail light. Find and clean an area first, then use the double-stick tape provided to secure the converter box in place.
Disconnect the original wiring harness from both tail lights. Plug the wiring kit end with the yellow wire into the mating plugs on the driver side taillight connector and the vehicle wiring harness connector. Route the wiring kit end with the green wire to the passenger side and plug it into the mating plugs on the passenger side taillight connector and the vehicle wiring harness connector.
Secure all loose wiring to the vehicle with zip ties as you work. Route the 4-way flat harness towards the front of the vehicle, securing it with zip ties. When reinstalling the tail light housings, position the wire harness between the housing and the vehicle body. Secure the remainder of the wiring harness in a secure area with zip ties to prevent damage and movement.
You can either install the 4-way flat harness into a 4-way flat bracket, or cut off the harness plug and splice the wires into your preferred style of trailer plug socket. The manual does not specify which socket styles are compatible or whether the bracket is included.
Mount the 4-way flat bracket or socket in a convenient location at the front of the vehicle. The manual does not specify exact mounting height, clearance requirements, or whether the bracket is included with the kit.
