Take just the CB radio to a Radio Shack store. Explain what you are trying to do. They should be able to give you the proper cable. It is just like a garden hose you need a cable with fittings on the ends to match your existing radio and cable that goes to the antenna. It should be very easy if you just take the radio to an electronics store like Radio Shack.
"Radio Shacks" that still exist do not carry anything other than cellphone stuff.. They are an empty shell of yesteryear.
