Wacker Neuson 5100064485 Trailer Wiring Harness

The Wacker Neuson Trailer Wiring Harness is a genuine OEM trailer wiring harness designed for PT6Y and PT6YT series pump units. As a factory-sourced component, it meets the original electrical specifications Wacker Neuson built into these machines — so you get the correct connector configuration, wire gauge, and circuit layout right out of the box. This harness fits multiple PT6Y and PT6YT configurations, including EPA Tier 4 variants, making it the go-to replacement across the PT6 pump lineup. When you need to restore trailer lighting and electrical connectivity to your pump unit, is the direct replacement to reach for.

Key Features

• Correct Connector and Circuit Layout: — Manufactured to the original electrical specification, with matching connector terminals and wire routing that align with the machine's existing harness path — no splicing or adapting required.
• Genuine OEM Quality: — Sourced directly from Wacker Neuson, this harness uses the same conductor gauge, insulation grade, and terminal spec as the original — ensuring stable signal continuity across all trailer lighting circuits.
• Broad PT6 Series Fitment: — Compatible with PT6Y and PT6YT series units, including standard and EPA Tier 4 configurations, covering a wide range of PT6 pump builds in a single part number.
• Restores Full Trailer Lighting Function: — A damaged or failed wiring harness can disable running lights, brake signals, and turn indicators on the trailer. Replacing it with 5100064485 brings all trailer lighting circuits back to proper operation.
• Road and Jobsite Compliance: — Trailer lighting is a legal requirement for towed equipment on public roads. Replacing a failed harness with a correct OEM unit keeps the machine transport-compliant and road-safe.

The trailer wiring harness is the electrical backbone connecting the tow vehicle's lighting system to the pump trailer — carrying signals for brake lights, turn indicators, and running lights. When this harness is cut, corroded, or damaged, trailer lighting fails entirely, creating both a safety hazard and a compliance issue when moving equipment on public roads. Installing a direct OEM replacement like the Wacker Neuson 5100064485 restores full electrical continuity to the trailer circuit and gets the unit back on the road correctly.
