Just purchased a 93 accord with no radio. Please answer a couple of questions for me. What year model honda radios will fit this car exactly like original. I know 89-93 should but what about 94-98? Second, I'm thinking of buying an original radio off ebay, but wonder about issues with the security code. If I purchase a used radio will I be able to get the security code for it and will the radio even work if it's not in the original vehicle it came from? Many thanks for the help.
