sorry I don't have a comment on this post, but I am trying to post one myself and can't seem to find a place anywhere else to post a message. Any way, I was wondering if someone could help me find a site that sells or lets you download a wiring diagram for a vintage blaupunkt radio installed in a 1954 vw bug? The only info I have on it is: Frankfurt TR T266801 (power Amp) Z11488 12316/112. Also, could anyone tell me which, if any of these numbers is the model number? Thanks
