wire to the factory installed water temperature switch wire. Do not confuse a water temperature switch
with a water temp erature sensor. If you are using a water temperature sensor do not use this input. See
Port B Wiring pin 1 for instructions.
Pin 8 – Low Oil Indicator Input –
Applying power to the tan wire will cause the low oil indicator to
activate. Insert the tan wire in pin position 8. Connect the other end of the tan wire to the factory installed
low oil switch. If your oil level switch goes to ground when activated you will need to install the ground
logic level converter contained in the port A wire harness kit. Follow the installation instructions provided
in the package.
Pin 9 – Remote Switch Input – When the blue wire is grounded the remote switch input will activate.
Insert the blue wire in pin position 9. Trim the other end of the blue wire to the desired length and connect
it to the blue wire on the remote switch using the connectors provided in the remote switch package.
Pin 10 – Not Used.
Pin 11 – Remote Switch Ground – Insert the black wire from the remote switch in pin position 11.
Alternately, you can connect the black wire from the remote switch to a good chassis ground instead of
running the wire back to pin 11 on the dash.
Pin 12 – Jack shaft RPM and Speedometer –
Insert the purple wire in pin position 12. Connect the other
end of purple wire to the red connector on the jack shaft sensor. See the section Jack Shaft Sensor and
Collar Installation for complete instructions on installing the jack shaft sensor.
Pin 13 – AC/DC power and Engine RPM input – When AC or DC power is applied to this wire the dash
will automatically turn on. Connect the red wire to the engine lighting coil. Using this method will get
power and the engine RPM signal from this single wire. If only DC power is available then connect the red
wire to a DC power source. Using a DC power source will require connecting the yellow wire on pin 15 to
get an engine RPM signal. See below for details.
Pin 14 – Ground – Connect the black wire to a solid chassis ground.
Pin 15 –Alternate Engine RPM input – If the red wire is connected to a DC power source you must
connect the yellow wire to a valid square wave tachometer output signal in order to get a proper engine
RPM reading. Do not connect this wire if the red wire is connected to the AC voltage output from the
engine lighting coil.
