The Bomag 78102107 Wiring Kit is a genuine OEM component designed for Bomag BW-series tandem rollers, including the BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ACH, BW 125 ADH, BW 135 AC, BW 135 AD, BW 138 AC, and BW 138 AD. Sourced directly from Bomag, this wiring kit is manufactured to the same specifications as the original harness assembly fitted at the factory. Verified fitment across the full range of compatible tandem rollers means you can order with confidence, knowing this kit will integrate correctly with your machine's existing electrical system.
Key Features
- Genuine OEM Electrical Integrity — manufactured by Bomag to exact conductor gauge, connector type, and insulation ratings — no guesswork on compatibility with your roller's electrical architecture
- Direct Drop-In Replacement — connectors, routing lengths, and termination points match the original harness, allowing straightforward installation without rework or splicing
- Broad Tandem Roller Coverage — fits BW 100, BW 120, BW 125, BW 135, and BW 138 series tandem rollers including AC and AD variants, covering a wide range of Bomag's articulated asphalt roller lineup
- Protects Electrical System Reliability — a failed or degraded wiring kit can cause intermittent sensor faults, control failures, or complete electrical shutdowns; replacing with a correct OEM kit restores stable, uninterrupted operation
- Safety-Critical Fit — on tandem rollers, the wiring harness feeds braking, propulsion, and vibration controls; using a correctly specced OEM kit ensures those systems receive clean, consistent signals
The wiring kit serves as the central electrical backbone for the roller's onboard systems, routing power and control signals between the engine, operator controls, sensors, and functional assemblies such as the vibration and propulsion circuits. A worn, corroded, or damaged wiring kit can produce symptoms ranging from erratic instrument readings and control dropouts to complete machine shutdowns — making timely replacement essential for safe, continuous operation. Installing a genuine OEM wiring kit ensures that every circuit path is restored to its original specification, keeping all connected systems communicating correctly.
