Why do some vehicles have more than one starter wire at the ignition switch?
The extra wire activates the fuel pump while cranking. The run position only lets the fuel pump run if it sees signals from the cam and/or crankshaft sensors.
one for the solenoid and a second for the distributor. the one for the solenoid is only active in the crank position where as the other is any time the key is in the run position or crank.
