Complete sheathed 7-way trailer wiring system designed for brake, lighting, auxiliary power, and rear harness distribution on compatible tandem-axle trailer applications.
Part Number: 88-BPUT-16 7-Way Round Blade System Tandem-Axle Brake Integration
Overview
The Novalite USA 88-BPUT-16 is a premium 7-way trailer brake and lighting harness kit built for clean trailer wiring installation from the tongue area through the rear lighting branches. This kit is organized around three harness modules: 01-8803-A, 02-8803-A, and 03-8803-A. It is intended to support electric brake wiring, lighting circuits, auxiliary power, and rear lamp connections on compatible tandem-axle trailer layouts where the harness length, connector style, and circuit configuration match the trailer.
R&P Service Insight
A full 7-way harness kit is a cleaner solution than piecing together loose wire, especially when the trailer needs electric brake wiring and rear lighting feeds routed through a protected mainline.
-
Cleaner Routing: Jacketed harness construction helps keep the trailer wiring organized from the front plug to the rear branches.
-
Brake Circuit Support: Designed for tandem-axle electric brake layouts with brake distribution through the mid-section harness.
-
Service-Friendly Layout: Modular harness sections can make installation, troubleshooting, and future replacement easier than loose-wire repairs.
R&P Knowledge Hub
Compatibility: Intended for compatible trailer applications using a 7-way round blade plug, electric brake wiring, and rear lighting circuits.
Vehicle / System Fit: Trailer-side 7-way brake and lighting harness system for compatible tandem-axle trailer builds, repairs, or rewiring projects.
Installation Notes: Verify harness length, wire routing, plug style, brake quantity, lamp connector style, and circuit color code before installation.
Performance Insight: A pre-organized harness system can reduce wiring mistakes, improve serviceability, and create a cleaner installation than building each circuit from loose wire.
