Item Description 12 to 24 Vdc à battery CCU Ä NMEA 2000 Å network Important Considerations The ECU must be connected to a 12 to 24 Vdc power source. To extend this cable, use the correct wire gauge (Power Cable Extensions, page 7). The NMEA 2000 power cable must be connected to a 9 to 16 Vdc power source. The CCU can be mounted in a non-submerged location near the center of the boat, in any orientation (CCU Mounting and Connection Considerations, page 2). The CCU must be located away from sources of magnetic interference. The helm control or compatible Garmin chartplotter and the CCU must be connected to a NMEA 2000 network using the included Tconnectors (NMEA 2000 Connection Considerations, page 2). If there is not an existing NMEA 2000 network on your boat, you can build one using the supplied cables and connectors (Building a Basic NMEA 2000 Network for the Autopilot System, page 8). Dual-Helm Layout Guidelines NOTE: This diagram is for planning purposes only. If needed, specific connection diagrams are included in the detailed installation instructions for each component. Hydraulic connections are not shown in this diagram. Item Description Helm control À 12 to 24 Vdc Á battery Pump  ECU à Important Considerations A dedicated helm control is not included in all autopilot packages. If you install the autopilot without a dedicated helm control, the autopilot CCU must be connected to the same NMEA 2000 network as a compatible Garmin chartplotter to configure and control the autopilot system. The ECU must be connected to a 12 to 24 Vdc power source. To extend this cable, use the correct wire gauge (Power Cable Extensions, page 7). The NMEA 2000 power cable must be connected to a 9 to 16 Vdc power source.

Hydraulic Layouts NOTICE If the steering system in your boat does not match any of the hydraulic layouts in this manual and you are unsure how to install the pump, contact Garmin Product Support. Before you start the pump installation, identify the type of hydraulic steering system in your boat. Each boat is different, and you must consider certain aspects of the existing hydraulic layout before deciding where to mount the pump. Important Considerations • The three hydraulic ports on the pump are 1/4 in. NPT. • Garmin recommends using T-connectors to connect the hydraulic lines to the pump. • To allow for easy pump disabling and removal, Garmin recommends installing shut-off valves in the hydraulic lines between the pump manifold and T-connectors. • Teflon® tape must not be used on any hydraulic fitting. • An appropriate thread sealant should be used on all pipe threads in the hydraulic system.
