The AutoLink Pro OBD Distance Sensor is the biggest revolution in distance sensor technology in the past 10 years. Its simple plug and play installation makes installing a Distance Measuring Instrument the easiest it has ever been.

All vehicles since 1996 have been made with an On Board Diagnostic (OBDII) plug that provides detailed information about the inner working of the vehicle. This plug, usually located within a foot or two of the steering wheel, allows a variety of devices to monitor the status of the vehicle while it is running.

By connecting to this plug, the AutoLink Pro sensor is able to determine when the vehicle is moving and send that information to the RAC distance measuring instrument, allowing it to keep track of the distance you have traveled as you drive.
