The cb will come with the power and ground wires. It may be wired to a cig lighter plug- cut that off and wire directly to the battery for clean power.
You will need to get coax for the antenna and figure out how you'll want to mount the antenna. After all hooked up check it with an SWR meter to properly tune the antenna and you're good to go.
