We always recommend selecting fuse slots that are rated between 10A-30A (in order to properly provide enough power to your dash cam). Always refer to the vehicle owner’s manual to avoid fuse slots that could pertain to certain safety features within your vehicle. For example, avoid fuses that deal with airbags, the horn, stability control programs, etc. Fuses that control certain elements such as the radio, garage door opener, sunroof, etc. are usually safe to use.

For almost all hardwire kits, there are 3 wires that need to be connected: a wire that goes to a constant fuse, a wire that goes to an ignition-switched fuse and another wire that goes to a metal ground bolt. A constant fuse remains on (and thus continues to provide power) even when the vehicle is off, an ignition-switched fuse turns off when the vehicle is off and a ground metal bolt prevents electric shock.
