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.

The ideal type of USB cables that are most common in the market is the USB type A and USB type B cable ports. The in-depth design and colloquial mobilization of data may affect the workability of the connectors, modules, and ports.
The format, shape, size, and in-built performance are solely connected to the other devices and accessories. In the case of a pair of USB-C cables, you may be looking at the same side of the turntables. The capabilities and working mechanism could be much different from the other belongings. The charging speed and transfer mechanisms may vary from cable to cable. So choose the USB types wisely. Otherwise, it will fail to diminish the programmable out of a layer of the CAN bus.
