The OBDII Bypass plug from Vaitrix is used to supply power source to any Vaitrix DIGIPEDAL module. Simply unfasten your OBDII port, plug this bypass into the port, and mount the open end of the bypass where your existing OBDII port was installed. 

This allows the Digipedal to run off of OBDII power without disrupting the use of your OBDII port for other procedures or activities.

This bypass is included with every Digipedal purchase, but you can purchase them for other uses.
