Yamaha - Oil Tank Harness - Oil System Electrical Component - 6R3-82521-90-00

Overview

On two strokes, the oil system is something you don’t take chances with. I’ve seen engines go into alarm or worse just from a bad connection between the tank and motor. When this harness is doing its job, everything communicates clean and you know the system’s telling you the truth. It’s one of those parts you don’t think about—until it stops working.

Key Features

• Dual 4-Pin Connections – Connects remote oil tank to engine using blue 4-pin connectors on both ends.
• Reliable Signal Transfer – Maintains accurate communication between oil tank and engine system.
• OEM Connector Fitment – Matches factory plugs for secure and proper connection.
• Marine-Grade Wiring – Built to withstand moisture, vibration, and harsh marine conditions.
