Wacker Neuson 5100012905 Connection Plug

The Wacker Neuson Connection Plug is a genuine OEM component designed for the RD24-100, RD27-120, RD40-130, and RD45-140 Tandem Roller series. As a factory-sourced part, it meets the exact electrical and mechanical specifications required by Wacker Neuson for these machines — no guesswork on compatibility. This plug fits across an extensive range of standard, canopy, and open-frame variants within these roller families, covering both earlier and current production models. When a connection plug fails, it can interrupt critical electrical circuits and bring your compaction work to a halt — sourcing the correct OEM replacement gets you back up fast.

Key Features

• OEM-Spec Electrical Connectivity — Manufactured to Wacker Neuson's exact connector specifications, ensuring correct pin configuration, seating depth, and contact integrity for the circuits it serves.
• Direct Plug-In Replacement — Engineered to seat and lock into the factory harness position with no splicing, adapter, or modification to the existing wiring.
• Broad Tandem Roller Coverage — Fits RD24-100, RD27-120, RD40-130, and RD45-140 Tandem Rollers across standard, canopy (C), and open-frame (O) configurations, as well as .3-series production variants.
• Protects Electrical System Integrity — A correctly seated connection plug maintains a secure, weather-resistant circuit link; a worn or damaged plug can cause intermittent faults, sensor errors, or complete circuit failure.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100012905 is the same component installed at the factory — not a close substitute.

A connection plug serves as a secure, removable link between two sections of an electrical circuit within the machine. It allows wiring harnesses and electrical components to be connected and disconnected cleanly during servicing without cutting or splicing wires. When a connection plug becomes corroded, cracked, or loses its locking retention, the circuit it carries can drop out intermittently or fail entirely — leading to sensor malfunctions, control issues, or electrical faults that are difficult to diagnose. Replacing a damaged plug with the correct OEM part restores a clean, stable connection and keeps the machine's electrical system functioning as intended.
