3.6 Analog Tachometer
The actuator harness contains a gray lead that can be connected to an
analog engine tachometer. You will not need to make this connection
if you are getting the speed source through an NMEA2000 network, or
if you have made an analog tachometer connection on the PCM CAN2
harness. See section 6.5 in Book 50 for more information on engine
speed source selection and wiring.
