Overview
The Garmin 010-12938-00 is a 4-pin threaded power and data cable for compatible ECHOMAP Ultra chartplotter/sounder combos. The harness is 6 ft (2 m) long and includes NMEA 0183 input/output for basic data sharing with other onboard electronics.
Use it for a new install when you want the wiring to stay tidy at the helm, or as a direct replacement when an existing cable has been cut, pinched, or pulled loose over time. The threaded collar helps keep the plug seated when the console is bouncing in chop.
Key features
- 6 ft (2 m) length for typical console and bracket mounts.
- 4-pin threaded connection that stays locked in place once the collar is snugged down.
- Power and data in a single harness to reduce extra adapters behind the dash.
- NMEA 0183 input/output for connecting to NMEA 0183 equipment.
- Fits ECHOMAP Ultra 102sv, 106sv, 122sv, and 126sv displays.
Compatibility and fit
This cable matches the 4-pin threaded power/data port used on the ECHOMAP Ultra 102sv, 106sv, 122sv, and 126sv. If your unit uses a different plug style or pin count, it will not thread on or make contact, so it is worth checking the connector on the back of the display before ordering.
Installation and setup
Run the cable with a drip loop behind the display, keep it away from sharp fiberglass edges, and secure it so the connector is not carrying the weight of the harness. Hand-tighten the threaded collar until it is snug.
When tying into a switch panel or distribution block, use appropriate circuit protection and clean, corrosion-resistant terminations. Leaving a little service loop makes it easier to pull the display for updates or winter storage without stressing the plug.
Electrical and system integration
The power leads connect to your boat's DC supply, while the NMEA 0183 input/output lines can pass navigation data to other NMEA 0183 devices such as a VHF radio, AIS, or an autopilot that accepts NMEA 0183 sentences. Keep splices dry and accessible, and label both ends before closing up the dash.
Use cases on board
This cable is a good match for center consoles, bass boats, and multi-station rigs where the ECHOMAP Ultra display is mounted a short run from the power distribution point and you want NMEA 0183 available in the same harness.
