The Wacker Neuson Trailer Wiring Harness is a genuine OEM component designed for PT6LT and PT6LT(I) series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this harness carries the correct connector configurations, wire gauges, and routing specs to integrate seamlessly with the factory trailer assembly on PT6LT Pump w/Trailer, PT6LT Pump w/Trailer T4, and PT6LT(I) Trash Pump units. As a genuine OEM part, the is built to the same standards as the original harness installed at the factory, so you can count on a clean, code-compliant electrical connection every time. When it comes to trailer lighting circuits on job-critical pump equipment, sourcing the correct OEM harness eliminates guesswork and keeps the machine transport-ready.
Key Features
- Correct Connector and Circuit Spec: — Engineered with the proper wire gauge, terminal types, and circuit layout to match the factory trailer electrical system on PT6LT series pumps — no splicing or adapter work needed.
- Genuine OEM Quality: — Manufactured by Wacker Neuson to the same electrical tolerances and insulation ratings as the original harness, ensuring consistent signal continuity across the trailer lighting circuit.
- Confirmed PT6LT and PT6LT(I) Fitment: — Verified for PT6LT Pump w/Trailer, PT6LT Pump w/Trailer T4, and PT6LT(I) Trash Pump configurations, covering both standard and Tier 4 variants.
- Restores Full Trailer Lighting Function: — A damaged or corroded wiring harness causes trailer lighting failure, creating a safety and compliance risk during road transport. This replacement restores brake lights, turn signals, and running lights to full operation.
- Road Transport Safety Compliance: — Trailer lighting is a legal requirement during equipment transport. Replacing a failed harness with the correct OEM part supports compliance with roadway lighting regulations for towed equipment.
The trailer wiring harness routes low-voltage electrical power from the tow vehicle to the PT6LT trailer's lighting system, supplying the brake lights, turn signals, and running lights required for safe and legal road transport. Over time, exposure to water, vibration, and debris at a pump jobsite can degrade the insulation and terminals, leading to intermittent or complete lighting failure. Replacing the harness with the correct OEM part restores the full electrical circuit and ensures the trailer meets roadway lighting requirements whenever the pump is moved between sites.
