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.

The BX8862 is a 6 to 6 coiled electrical cable kit (part 294-1111) that connects a towing vehicle to a trailer's electrical system. It includes a black plastic 6-pin connector (part 294-0902) and is designed to transmit turn signals, brake signals, tail lights, ground, battery power, and backup signals between the vehicle and trailer.
Yes. The BX8862 is compatible with 4-way, 5-way, 6-way, and 7-way connectors on both the vehicle and trailer sides. The wiring reference sheet shows pin configurations for all these connector types.
The BX8862 uses the following standard trailer wiring colors: Green for right turn signal, Yellow for left turn signal, White for ground, Brown for tail/marker lights, Blue for electric brake power, Red or Black for battery, and Purple for backup lights. Each wire connects from the corresponding circuit on the towing vehicle to the matching function on the trailer.
Wire gauge requirements vary by connector type and function. For 4-way and 5-way connectors: Green (right turn) 18 gauge, Yellow (left turn) 18 gauge, White (ground) 16 gauge, Brown (tail light) 18 gauge, Blue (brake) 18 gauge, Red/Black (battery) 12 gauge, Purple (backup) 16 gauge. For 6-way and 7-way connectors: Green 16 gauge, Yellow 16 gauge, White 12 gauge, Brown 16 gauge, Blue 12 gauge, Red/Black 12 gauge, Purple 16 gauge.
The white ground wire should be attached to a metal, uncoated, rustproof ground point on both the vehicle and the trailer. Ensure the ground connection is solid, as a bad, loose, or faulty ground is a common cause of electrical problems.
The blue wire is the electric brake signal wire. On the vehicle side, it connects to the electric brake control. On the trailer side, it connects to the break away switch or electric brake system.
The red or black battery wire connects from the fuse block or a fused battery lead on the towing vehicle to the break away kit, interior lights, and battery charger on the trailer.
Incorrect wiring may result in blown fuses, damaged wiring, fire, or bodily injury. Blue Ox recommends installation by a trained professional and will not be responsible for personal property damage or bodily injury caused by incorrect wiring or misuse of the product.
Dim or incorrect lights can be caused by: (A) a bad, loose, or faulty ground on either or both vehicles—ensure the ground connection is solid; (B) a short circuit in the system on either or both vehicles; (C) a towing vehicle alternator that is too small to supply the extra power; (D) towing vehicle wiring that is too light to handle the extra power requirements; or (E) the towing vehicle may require a heavy-duty flasher unit to handle the extra load.
Lights not working can be caused by: (A) a wiring error to the bulb and sockets; (B) a bad, loose, or faulty ground on either or both vehicles—pay special attention that the ground is solid; (C) a blown fuse in the towing vehicle—check continuity of all wires to ground to ensure the harness is not short circuited; or (D) a bad connection between the female and male plugs—check for a solid connection.
Yes. Blue Ox recommends using a circuit tester to verify connections. Wire colors may vary by manufacturer, so testing ensures you have connected the correct wires to the correct functions on both the vehicle and trailer.
Yes, the BX8862 is compatible with all four connector types on both vehicle and trailer sides.
Green (right turn), Yellow (left turn), White (ground), Brown (tail lights), Blue (electric brake), Red or Black (battery), and Purple (backup lights).
Blue Ox recommends installation by a trained professional. Incorrect wiring may result in blown fuses, damaged wiring, fire, or bodily injury.
Check the ground connections on both vehicles—ensure they are solid and metal-to-metal. Also verify the fuse in the towing vehicle is not blown and that all wire connections between plugs are secure.
16 gauge for 4-way and 5-way connectors; 12 gauge for 6-way and 7-way connectors.
Possible causes: (1) Bad, loose, or faulty ground on either or both vehicles—ensure the ground is solid; (2) Short circuit in the system on either or both vehicles; (3) Towing vehicle alternator too small to supply extra power; (4) Towing vehicle wiring too light to handle extra power requirements; (5) Towing vehicle may require a heavy-duty flasher unit to handle the extra load.
