Key Features

• Genuine OEM Electrical Integrity — Manufactured to Wacker Neuson's original connector specifications, delivering the correct contact resistance and mating geometry required for dependable signal and power transfer in a compaction environment.
• Direct-Connect Replacement — Plugs into the existing wiring harness connector point without modification, maintaining the original locking and sealing interface of the factory harness.
• Broad Tandem Roller Coverage — Fits RD24-100, RD27-120, RD40-130, and RD45-140 series machines, including C (cab) and O (open) variants across first, second, and third build generations.
• Protects Electrical System Continuity — A failed or corroded connection plug can cause intermittent faults, control signal loss, or complete circuit failure; replacing it with the correct OEM part restores clean, uninterrupted electrical flow.
• Electrical Safety Compliance — Using the genuine OEM connector maintains the rated insulation and locking retention of the original harness design, preventing unintended disconnection or arcing under machine vibration.

A connection plug serves as the interface point between two sections of an electrical wiring harness, creating a secure, insulated junction that carries power or control signals between machine systems. On tandem rollers like the RD series, these connectors are exposed to constant vibration, moisture, and heat cycling, all of which can degrade contacts and compromise the electrical circuits that control drum drive, compaction controls, and operator safety systems. A worn or damaged connection plug can produce intermittent faults or total circuit failure, making timely replacement with the correct OEM part essential to keeping the machine running as intended.
