Does your vehicle have a Mag/VR or Hall style Crank Sensor?
Magnetic(Mag) or Variable Reluctance(VR) style sensors typically have two
wires. Hall style sensors typically have three wires. Vehicles have either a Mag/VR or
a Hall style Crank Sensor, not both. If your vehicle has a Mag/VR sensor, the two Hall
sensor wires can be eliminated. If your vehicle has a Hall sensor the four Mag sensor
wires can be eliminated. Connect the Crank Sensor as shown below in Figure 3.
