6.6 Autopilot Connection (Optional)
Autopilots certified by SeaStar as compliant with the EPS system will
simply connect to an available CAN2 network tee. The connection
harness is supplied by the autopilot manufacturer. Refer to the
manufacturer’s instructions for additional information.
If you are using analog tachometers as your engine speed source, you
will need to connect the gray and black tachometer leads on harness
CM20304 (see figure 6-11). Connect the gray wire to the port engine
analog tach input, and the black (with gray stripe) wire to the starboard
analog tach input. The analog tachometer connection is not recommended
for triple or quad engine applications.
The leads are fitted with Molex Perma-Seal bullet connectors. The male
connector is Molex P/N 191640040 and the female connector is
191640054. Crimp and seal the mating connectors (not supplied by
SeaStar) onto your tachometer leads, per the manufacturer’s
instructions, and push together to connect.
If you are getting your input source from an NMEA 2000 network
(section 6.5.1) then you need to leave the gray and black wires
connected to each other as shown in figure 6-11.
