• An orange wire provides power to the fuel pump.
Ground is through the frame via a green wire
paired with the orange wire.
• The green wire grounds to the engine block,
along with the rest of the engine harness.
• The orange wire provides battery voltage,
unfused, from the regulator when the key is in
any position other than STOP. This is the same
circuit that powers the fuel pump.
• A single click can be heard and felt at the fuel
shut-off solenoid each time it turns on or off.
