2 Route the bare-wire end of the ECU power cable to the boatbattery.If the wire is not long enough, it can be extended (PowerCable Extensions, page 7).3 Connect the black wire (-) to the negative (-) terminal of thebattery, and connect the red wire (+) to the positive (+)terminal of the battery.4 After you install all of the other autopilot components,connect the power cable to the ECU.Power Cable ExtensionsIf necessary, the power cable can be extended using theappropriate wire gauge for the length of the extension.Item DescriptionÀ FuseÁ BatteryÂ 9 ft.

(11 m)Pump InstallationMounting the PumpBefore you can mount the pump, you must select a location(Pump Mounting Considerations, page 2) and determine thecorrect mounting hardware (Tools Needed, page 1).1 Hold the pump in the intended mounting location and markthe locations of the mounting holes on the mounting surface,using the pump as a template.2 Using a drill bit appropriate for the mounting surface andselected mounting hardware, drill the four holes through themounting surface.3 Secure the pump to the mounting surface using the selectedmounting hardware.Connecting the Hydraulic Lines to the PumpRefer to the layout diagrams for assistance (Hydraulic Layouts,page 4).1 Disconnect the necessary lines from the hydraulic system.2 Add a T-connector to the starboard and port lines of thesystem between the helm and the steering cylinder.NOTE: If the boat has a power-assist module, you must addthe T-connectors between the power-assist module and thesteering cylinder.3 Complete an action:• If the boat does not have a power-assist module, addenough hydraulic hose to connect the return fitting on thehelm to the center pump fitting.• If the boat has a power-assist module, add a T-connectorto the return line of the system between the power-assistmodule and the helm. A return line should already existbetween the helm and the power-assist module.4 Add hydraulic hose to the unused fitting on each T-connector,with enough hose to connect the T-connector to the pumpfittings.5 Connect the port and starboard line T-connectors to theappropriate pump fittings, as shown in the layout diagram foryour hydraulic configuration.6 Install the Shadow Drive in the port or starboard hydraulicline between the helm and the T-connector (Installing theShadow Drive, page 8).7 Install a shut-off valve (not included) on each hydraulic linethat connects directly to the pump.Bleeding the HydraulicsNOTICEThis is a general procedure for bleeding a hydraulic steeringsystem. Refer to the instructions provided by the manufacturerof the steering system for more-specific information aboutbleeding the system.Before you bleed the hydraulic system, you should verify that allhose connections are complete and fully tightened.1 Select an option:• If the helm reservoir contains insufficient fluid, fill it asneeded.• If the helm reservoir contains excess fluid, remove theexcess to avoid fluid overflow during the bleeding process.2 Insert a bypass hose between the cylinder bleed ports.TIP: If you use a clear plastic hose for this bypass, you canobserve air bubbles during the bleeding processes.3 Manually steer the helm fully to port.4 Open both bypass valves at the cylinder fittings.5 Manually turn the helm slowly to port over three minutes.TIP: You can stop turning when you no longer see air movingthrough the bypass hose.7
