You should now have assemblies that look like those shown in Figure 3c. Repeat these steps for the
remaining Ping))), and IR Sensor assemblies.
Figure 3c
Connect the appropriate cables to each of the sensors. Be sure to observe proper polarity on the Ping

into the receptacle. Be sure to fully insert them – they should "click" into place.
Set these assemblies aside for now.
