1. ENGINE STARTING CIRCUIT What type(s) of circuits is this wire installed
in? (i.e., YELLOW with a RED Stripe Wire)?
CONNECTIONS - located between the Key What components would it connect togeth-
Switch or Starter Button on electric start er?
motors and the engine-mounted Starter
Solenoid on the outboard or inboard en-

gine's Oil Pressure Sensor and the Oil Pres-
sure Gauge on the cockpit Instrument Pan-
el.
3. FUEL LEVEL CIRCUITS What types of circuit(s) is this wire in-
stalled in? (i.e., PINK Wire) What compo-
CONNECTIONS - located between the Fuel nents would it connect together?
Tank Sender on top of the fuel tank and the
Fuel Gauge on the Instrument Panel
