Use this Y-splitter cable if you need to connect an additional OBD-II device at the same time as your AutoPi Dongle or AutoPi Telematics Unit. You can also use this cable to make a stealth installation of your AutoPi device behind the dashboard, meanwhile the vehicle still has one free OBD-II port. The cable has direct pass through on all 16 pins and a length of approximately 30cm.
