Garmin MotorGuide 4-Pin Adapter

The Garmin MotorGuide 4-Pin Adapter is the essential bridge between modern Garmin fishfinder and GPS combo units and MotorGuide trolling motors. If you've invested in a quality Garmin electronics suite and run a MotorGuide trolling motor on your boat, this adapter cable eliminates compatibility obstacles that would otherwise prevent seamless integration. Whether you're upgrading an existing setup or rigging a new vessel for serious shallow-water fishing, this connector ensures your navigation and sonar systems work in tandem with your motor controls.

The 4-pin connector architecture was engineered specifically to match the proprietary transducer interface found on MotorGuide motors, allowing Garmin fishfinders to receive depth, temperature, and positioning data without aftermarket workarounds. This purpose-built adapter cable delivers clean signal transmission and mechanical reliability in the harsh marine environment—salt spray, vibration, and temperature swings won't degrade the connection. The compact 0.13 lb design adds negligible weight to your console or helm station while maintaining the robust construction standards both Garmin and MotorGuide demand of their product ecosystems.

Serious anglers and weekend boaters alike benefit from this straightforward, OEM-engineered solution that eliminates guesswork during installation. The adapter works with Garmin fishfinder/GPS combo units equipped with 4-pin transducer ports and any MotorGuide trolling motor featuring the standard 4-pin transducer socket. Installation is plug-and-play—no crimping, splicing, or custom wiring required. This is the authentic Garmin part (MPN 010-11979-00), backed by manufacturer support and proven reliability on the water.
