The Bomag 78102108 Wiring Kit is a genuine OEM component designed for Bomag BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ADH, BW 135 AD, BW 138 AC, BW 138 AD, and related tandem roller models. Sourced directly from Bomag, this wiring kit delivers the exact connector layout, wire gauging, and routing configuration engineered for these machines — no guesswork on compatibility. As an authentic OEM part, it meets the same build standard as the original harness installed at the factory, ensuring every circuit connects as intended. If your tandem roller is showing electrical faults, intermittent power loss, or wiring damage from wear or impact, this kit is the correct service replacement to restore full electrical function.
Key Features
- OEM Electrical Integrity — Manufactured to Bomag's original wiring specifications, with correct wire gauges, insulation ratings, and connector types matched to the machine's electrical system demands.
- Direct Harness Replacement — Engineered to route and connect exactly as the original, allowing straightforward installation without splicing, adapting, or rerouting existing circuits.
- Broad Tandem Roller Coverage — Compatible with BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ADH, BW 135 AD, BW 138 AC, BW 138 AD, and additional BW-series tandem roller variants.
- Restored Electrical Reliability — A degraded or damaged wiring kit can cause erratic controls, sensor failures, or complete electrical shutdown; this replacement brings circuits back to full operating condition.
- Electrical System Safety — Correct wire sizing and insulation prevent overheating, short circuits, and potential electrical hazards — critical on ride-on compaction equipment where electrical faults affect operator controls and safety systems.
A wiring kit bundles the harness, connectors, and associated wiring components that carry power and control signals to the machine's electrical systems — including drive controls, vibration systems, lighting, and instrumentation. On tandem rollers like the BW-series, the wiring harness is the central nervous system of the machine: when it degrades through abrasion, heat cycling, or connector corrosion, operators can experience unpredictable control response, warning light faults, or complete loss of function in critical systems. Replacing a worn or damaged harness with a correct OEM wiring kit ensures all circuits are restored to their designed capacity and routing, keeping the machine operating safely and predictably on the job.
