It is a very prudent choice to connect the dash cam with the OBD2 cable alongside the port. This can save a huge sum of energy that is used by these devices. The link between these two devices can spark the vehicle’s energy consumption. Let us discuss the complete battery magnitude of the dash cam with the notorious OBD2 power cable,
Find the OBD2 port
The very initial step is to locate the OBD2 port in the vehicle. In general, it is located to the left of the steering wheel at the driver’s side, underneath the dashboard. You can seek help from the car’s manufacturing manual to detect the exact location of the OBD2 port.
