Overview
The Garmin 010-11055-02 is a 66 ft (20 m) CCU/ECU interconnect replacement cable used on Garmin GHP 10 autopilot installations when you need more distance between the Course Computer Unit (CCU) and the Electronic Control Unit (ECU).
On a typical GHP 10 install, the standard CCU to ECU run is 16 ft (5 m). This replacement cable takes the place of that main interconnect so you can route the CCU where it works best on the boat while keeping the ECU closer to the pump and power connections.
The interconnect harness includes a section with color-coded bare-wire leads used for the tachometer input, Shadow Drive, and alarm buzzer connections that tie into the autopilot system.
Key features
- 66 ft (20 m) overall length for longer CCU-to-ECU cable runs
- Replacement CCU/ECU interconnect cable format for Garmin GHP 10 installations
- Supports mounting the CCU farther than 16 ft (5 m) from the ECU when layout demands it
- Dedicated link between the CCU and ECU for the autopilot system
- Color-coded bare-wire section for connecting Shadow Drive, alarm buzzer, and tachometer wiring
- Useful for routing across bulkheads, under decks, or between compartments when planning service loops and clean cable management
Compatibility and fit
This cable is intended for Garmin GHP 10 autopilot systems that use the CCU and ECU architecture with a CCU/ECU interconnect harness. It replaces the main CCU-to-ECU interconnect when the standard length does not reach your chosen mounting locations.
It does not change other system cabling limits, such as ECU-to-pump placement, so plan the layout with the ECU staying where the hydraulic pump wiring and power connections remain practical.
Installation and setup
Route the cable on a path that avoids sharp edges, moving parts, and high-heat areas. Use chafe protection at pass-throughs, secure the run at regular intervals, and leave a small service loop at the CCU and ECU so connectors are not carrying strain.
Where the harness transitions to bare-wire connections, take the same care you would with any helm or engine-room wiring: make solid terminations, seal them against moisture, and keep the connections supported so vibration does not work-harden the conductors.
Use on board
This length is a practical match when the ECU ends up in an engine space or machinery area and the CCU needs to be mounted closer to the vessel centerline, forward, or away from magnetic interference. It is also common on refits where the original component locations change but you want to keep the autopilot wiring straightforward.
