OPTIONAL WIRE HARNESS
Engines supplied with a wire harness have a Packard
#2973422 five terminal female plug on the harness.
• Terminal 1 has a brown wire coming from it and is used to
signal low oil pressure. When low oil pressure is detected,
Terminal 1 becomes a ground. Otherwise it is open.
• Terminal 2 has a yellow wire coming from it and is used to
kill the ignition. Connect this terminal to ground and the
ignition will be shut off.
• Terminal 3 isn't used.
• Terminal 4 has a white wire coming from it. Connect this
terminal to +12 V DC and the carburetor will allow fuel to
flow. Turn off the +12 V supply, and the fuel solenoid will
close, stopping the flow of fuel.
• Terminal 5 has an orange wire coming from it. This wire is
used to start the engine. Supply +12 V DC to this terminal
and the starter solenoid will engage. Turn off the +12 V
supply, and the starter will disengage.
Figures 6-6 through 6-9 show the proper connections for the
wiring harness and how it is routed.
