The OBD2 Splitter Y Cable allows 2 devices to be connected simultaneously. The existing OBD2 connector plugs into the male connector of your y adapter so you can easily connect your OBD2 Keep Track Bolt GPS Tracker to a power source while leaving access to the vehicle's computer for downloading accessing vehicle codes.
The OBD II Y Cable Splitter mounts under the dashboard and easily snaps into the existing OBD2 position. All 16pins are connected.
