I recently purchased a 2005 New Beetle GLS Convertible. I have the CD changer from my 2001 Jetta but cannot find the wiring harness in the Beetle to install. I checked the trunk on left side behind trim panel and also in the center console just in case it was wired for the changer in console. I cannot find the harness anywhere. Does anyone know if I am just looking in the wrong spot or was the cable an option. Thanks in advance for your help.
