15-Foot 3-in-1 Air Line & Electrical Cable Assembly

The Power Products 3-in-1 tractor-trailer assembly is designed to keep three essential connections organized in one unit.

Instead of routing separate air hoses and an electrical cable independently, the assembly uses protective spiral wrapping to hold the lines together.

This helps simplify cable management behind the truck cab and keeps the tractor-trailer connection area organized during daily use.

The 15-foot nominal assembly length is suitable for compatible configurations where the installed connection routing and trailer articulation requirements call for that length.

Important: Verify the original assembly length and required cable routing before purchasing. Different truck wheelbases, cab configurations, fifth-wheel positions, and trailer setups may require different lengths.

Three Essential Tractor-Trailer Connections

This Power Products combination assembly contains the three lines commonly needed between a highway tractor and trailer.

Red Emergency / Supply Air Line

The red emergency air line supplies compressed air from the tractor to the trailer air system. Properly functioning emergency air connections are essential for maintaining the trailer's air supply and parking brake operation.

Blue Service / Control Air Line

The blue service air line carries pneumatic brake control signals from the tractor to the trailer. A properly sealed service connection is important for consistent trailer service brake operation.

Green Trailer Electrical Cable

The green electrical cable connects the tractor and trailer electrical systems. It supports the functions provided by the compatible installed trailer electrical connection, including lighting and applicable ABS circuits.

All electrical connectors must match the vehicle's existing socket configuration.

Rubber Air Hoses for Heavy-Duty Commercial Trucks

The Power Products assembly uses rubber air brake hoses intended for commercial vehicle applications.

Heavy-duty tractor-trailer air hoses are exposed to repeated movement, road contaminants, vibration, changing temperatures, and frequent trailer connections.

Inspect the air hoses regularly for:

• Cracks or cuts in the hose material
• Abrasion caused by contact with surrounding components
• Air leaks around hose fittings and couplings
• Kinking, twisting, or excessive stretching
• Damage resulting from improper line routing

Damaged air lines should be repaired or replaced before the vehicle returns to service.

Spiral-Wrapped Tractor-Trailer Air & Electrical Lines

The assembly features a spiral-wrapped design that holds the electrical cable and both air hoses together.

Benefits of the integrated design include:

• More organized hose and cable routing
• Reduced tangling between individual connections
• Convenient replacement of the complete connection bundle
• Simplified visual inspection of tractor-trailer lines
• Practical cable management for commercial truck fleets

The assembly must still be properly supported and routed to prevent dragging, snagging, or interference during turns.

Heavy-Duty Semi Truck Applications

The Power Products 15-foot combination assembly is intended for compatible commercial trucks using the corresponding tractor-to-trailer air and electrical connections.

Potential vehicle applications include properly equipped:

• Freightliner Cascadia and other Freightliner highway tractors
• Kenworth T680, T880, W900, and related models
• Peterbilt 579, 389, 567, and other highway tractors
• Volvo VNL commercial trucks
• International Class 8 tractors
• Mack highway tractors
• Western Star commercial trucks
• Other compatible heavy-duty tractor-trailer combinations

Fitment Notice: The vehicle model alone does not establish compatibility. Confirm the required assembly length, trailer electrical connection, air line fittings, and routing clearances before ordering.

Installation & Fitment Verification

Before installing the Power Products combination assembly, compare its length and connection configuration with the original equipment.

Verify the trailer electrical plug arrangement, air brake hose fittings, air line routing, and available clearance during full tractor-trailer articulation.

Secure the lines with suitable supports and keep them clear of hot components, sharp edges, and moving equipment.

After installation, test the tractor-trailer electrical functions and inspect the air system for leaks according to the vehicle manufacturer's procedures.

Safety Warning: Heavy-duty air brake systems contain stored compressed air and must be serviced using approved safety procedures. Properly secure the vehicle and depressurize applicable circuits before disconnecting air brake components.

Professional Installation Recommended: Tractor-trailer electrical and air brake connections are safety-critical. Installation and testing should be completed by qualified personnel.
