Multiquip EE50818 Deutsch 3 Position Connector

The Multiquip EE50818 Deutsch 3 Position Connector is a genuine OEM electrical connector designed for HTX6H, PRX, and STX6H ride-on power trowel models. As a direct OEM replacement, this connector meets the original wiring harness specifications for these machines, ensuring a secure and correct mating connection every time. Sourced directly through Multiquip's authorized parts program, EE50818 is the exact component your trowel left the factory with. If you're tracing an electrical fault or completing a harness repair on an HTX6H, PRX, or STX6H, this is the part to have on hand.

Key Features

• Genuine OEM Deutsch Connector — Manufactured to the same locking and sealing specifications as the original, ensuring a weatherproof, vibration-resistant connection in harsh concrete finishing environments.
• Correct 3-Position Terminal Configuration — Matches the factory pin count and housing geometry for a drop-in installation with no splicing or harness modification needed.
• Confirmed Fitment for HTX6H, PRX, and STX6H — Verified for Multiquip ride-on power trowels across the HTX, PRX, and STX series, covering both hydrostatic and hybrid power float platforms.
• Protects Electrical Integrity — A failed or corroded connector can cause intermittent blade control loss or engine electrical faults; replacing with a correct OEM connector restores full circuit continuity.
• Electrical Safety Compliance — Using the correct OEM-rated connector maintains the original insulation and current-carrying rating of the circuit, which is critical on high-cycle control systems like ride-on trowel blade pitch and drive circuits.

The Deutsch 3 Position Connector is a sealed, multi-pin electrical connector used within the wiring harness of ride-on power trowels to join control circuits between components such as sensors, solenoids, and control modules. Its locking housing and weather-sealed design protect the electrical connection from moisture, concrete dust, and vibration — conditions that are constant on a finishing site. When this connector degrades, corrodes, or fails to seat properly, the result is an unreliable or broken circuit that can cause erratic blade behavior, loss of drive response, or electrical fault codes that bring the machine to a stop.
