Amazon: Alpine CDE 102 103BT 121 122 123 124 125 125BT Aug 05, 2013I have an Alpine CDE-123 that the guy at the install place told me you just can't hardly get a wire harness for these unless they are straight from Alpine and they normally won't give you one without proof of purchase (receipt). I bought mine off a guy that took it out of his wifes wrecked car, but he didn't get the harness out.4.1/5(16)Price: $5 alpine cde 123 | eBay Find great deals on eBay for alpine cde 123.
