Yes, child's play. Mine is wired so it is permanently live so I can use it when the engine isn't running.
I searched the bay for one with a waterproof cover, I have a convertible, for additional protection. It came complete with simple bracket. A wire to a suitable earth point, plenty of choice under the dash another with inline fuse to +ve on battery.
Just make sure when connecting you put them the correct way round or you will blow the fuse when you first use it. Just saying this for info as I'm sure you wouldn't be clumsy enough to get it wrong unlike some people ( hangs head in shame) ππ
