External TPMS Installation 
Note:  Install antenna and turn on monitor before installing sensors, for capturing 
and displaying the newly pressurized sensor readings during installation 
1. Monitor 
•  Driver side on dash is a better signal monitoring location than the center of the dashboard 
•  Turn on/off monitor with the battery switch in the back side 
•  After switched on, the monitor will clear all prior readings and show “- -“ for each tire 
•  Turning on monitor after sensor installation may need up to two hours for sensor readings to 
appear; the sensors send few signals when vehicle is not moving for saving battery power. 
2. Sensor vs. Tire Location Mapping 
4 / 6 / 8-tire Truck / Motorhome Sensor Mappings 
2 / 4 / 6-Tire Car / Trailer Sensor Mapping
