Once you've hacked everything, why not take it outside and hack your car? This cable enables access to the pins on your car's OBD-II connector. It has an OBDII connector on one end and a DE9 (or "DB9") female serial connector on the other. The overall length of the cable is 5'. Note: This cable is not meant to be plugged directly into a computer's serial port. It is designed to connect to a specific hardware interface.
