Wacker Neuson 5000163625 Honda Oil Switch Wiring Harness

The Wacker Neuson is a genuine OEM Honda Oil Switch Wiring Harness designed for the CRT36 series ride-on concrete trowels. Sourced directly from Wacker Neuson, this harness is built to the exact electrical specifications of the original component, ensuring correct signal routing between the Honda engine oil pressure switch and the machine's protection circuitry. Compatible models include the CRT36-23K-H, CRT36-24A-H, CRT36-24A-E, and CRT36-25K-H, covering both keyed and electric-start variants of the 915mm/36-inch ride-on high-speed trowel lineup.

Key Features

• OEM Electrical Specification: — Manufactured to the original wiring gauge, connector type, and insulation rating — no signal loss or resistance mismatch at the oil switch circuit.
• Direct Connector Match: — Plugs into the Honda engine oil pressure switch and machine harness using the factory connector housings, requiring no splicing or adapter work.
• CRT36 Series Fitment: — Confirmed fit for CRT36-23K-H, CRT36-24A-H, CRT36-24A-E, and CRT36-25K-H ride-on concrete trowels across multiple production years.
• Protects Engine from Oil Starvation Damage: — A functioning oil switch circuit allows the machine to shut down automatically when oil pressure drops critically low; a failed or miswired harness disables this protection entirely.
• Engine Safety Circuit Integrity: — Correct harness routing and connector seating are essential for the oil pressure shutoff to operate as intended, protecting the Honda engine against low-oil events on the finishing deck.

The Honda Oil Switch Wiring Harness carries the electrical signal from the Honda engine's oil pressure switch to the machine's control system. When oil pressure falls below a safe threshold, this circuit triggers an automatic engine shutoff to prevent internal engine damage — a critical protection feature during sustained concrete finishing operations. If the harness becomes damaged, corroded, or develops a poor connection, the oil pressure shutoff function may fail silently, leaving the engine exposed to low-oil conditions without any warning or automatic response.
