More about this item

Sierra 18-99620 Wiring Harness

The Sierra Wiring Harness (Part Number 18-99620) is an aftermarket replacement harness for Johnson and Evinrude outboards, specifically covering 1986 and 1987 models in the 35, 40, 48, and 50 HP range. It uses a round plug connector, which is the correct configuration for these model years. Getting the connector style right matters here since round and square plug harnesses are not interchangeable.

This harness crosses to CDI part number 413-3211 and Johnson/Evinrude OEM part number 583211, so if you are working from a parts manual or a previous order, those numbers confirm you are looking at the right replacement. Sierra builds their marine electrical components to meet or exceed OEM specifications, making this a reliable option when the original harness has corroded, shorted, or simply given up after decades of saltwater exposure.

Wiring harness replacement on outboards of this era is a common repair. Corrosion works its way into connectors and insulation over time, causing intermittent electrical faults, ignition issues, and charging problems that can be frustrating to diagnose. A fresh harness eliminates a lot of variables at once.

Confirm your engine's model year and horsepower rating against the 1986-1987, 35/40/48/50 HP fitment range before ordering. The round plug configuration must match your existing setup.
