Overview

The Garmin 010-11055-00 is a 16 ft (5 m) CCU to ECU interconnect cable used in Garmin GHP 10 autopilot installations. It links the Course Computer Unit (CCU) to the Electronic Control Unit (ECU) and gives you enough length to route cleanly through rigging tubes, under decks, or behind a helm without putting the system components in the same compartment.

This harness also includes a color-coded, bare-wire section used for the typical on-board connections that tie into the autopilot system during install, such as tachometer signal, Shadow Drive, and the alarm buzzer wiring. It is the right fit when you are replacing a damaged interconnect, correcting an install that was pulled tight, or re-routing to a better mounting location.

Key features

• 16 ft (5 m) overall length for CCU to ECU placement flexibility on a boat
• Connector-terminated interconnect for the CCU to ECU link in a GHP 10 autopilot system
• Color-coded bare-wire leads for wiring into supporting functions like tachometer input, Shadow Drive, and alarm buzzer connections
• Commonly used with Garmin GHP 10 and GHP 10V autopilot systems that use separate CCU and ECU modules
• Useful for clean refits when the original routing is too short, chafed, or no longer reaches after equipment relocation

Compatibility and fit

This cable is for Garmin autopilot installations that use a separate CCU and ECU, such as the GHP 10 family. It is not a transducer cable and it does not replace NMEA 2000 drop cables or network backbone wiring. Match it to the interconnect used between your CCU and ECU and confirm you have the correct style for your specific autopilot generation before ordering.

Installation and setup

Plan the route from the ECU location near the pump or steering gear to the CCU mounting area, then confirm you can stay within the 5 m run without stretching the harness. Support the cable along its path so it is not hanging by the connectors, and keep it away from sharp edges and moving steering components. The bare-wire section is where you make the helm and accessory splices, so leave enough access to work cleanly and seal connections properly for the marine environment.

Who it suits on board

This is a good match for owners and installers doing a tidy GHP 10 refit where the ECU is mounted low and aft and the CCU needs to live in a drier, more protected space. It also fits boats that see vibration and constant access panels, where replacing a tired interconnect cable prevents intermittent heading and steering issues caused by strained wiring.
