GHP Autopilot Extension Cables
The use of extension cables will depend on the size of the boat, GHP Autopilot model, and the mounting locations of the Course Computer Unit (CCU) and the Electronic Control Unit (ECU)/ Smart Pump.
ECU to CCU Extension
GHP 10 and GHP Reactor Hydraulic Autopilot Systems: this cable allows the Course Computer (CCU or Reactor) to be mounted further from the ECU (Electronic Control Unit), the cable between the Interconnect Cable and the CCU/Reactor
5 meter cable 010-11156-00
15 meter cable 010-11156-01
20 meter cable 010-11156-02
GHP 12, 20, all other Reactor/Reactor 40 Autopilot Systems: this cable allows the Course Computer (CCU or Reactor) to be mounted further from the ECU (Electronic Control Unit), the cable between the Interconnect Cable and the CCU/Reactor
5 meter cable 010-11156-30
15 meter cable 010-11156-31
25 meter cable 010-11156-32
If the bare wire connections for the tachometer buzzer, shadow drive, or the "accessory on" wires need to be extended, any bare wires can be used as long as it is the same gauge as the wire that is to be extended.
ECU Power Cable Extension
If the ECU's power cable needs to be extended, bare wires can be used, but the gauge of the extension must match the total distance of the power cable.
Use 12 gauge wire for up to a 10 feet extension
Use 10 gauge wire for a 10 to 20 feet extension
Use 8 gauge wire for a 20 to 25 feet extension
For longer extensions, such as routing through a switch in the cabin, consider using a high current relay to keep the battery lead short
NOTE: For 1.0, 1.2, 2.0 and 2.1L Garmin Pumps, the pump's power and encoder cables cannot be extended. The pump or ECU will need to be mounted close enough to use the cables that are provided.
