that are to be connected as follows:
1 Connect the Red lead of the ODO 0 cable to the vehicle’s
odometer pulse signal.
2 Connect the Black lead of the ODO 0 cable to chassis ground.
3 Connect the HEADING SENSOR cable to the heading sensor.
NOTE
Position the magnetic-mount GPS antenna 18 inches (45.7 cm) away from
other antennas. The GPS antenna must have an unobstructed view of the
horizon for best performance.
