Glad to hear things are working properly.  I think if you did a search on this site, you'd probably find a couple of dozen threads that start with the words, 'Can anybody tell me what this ___ (insert color) wire is for?'   It seems that most Z's fell prey to D-I-Y AM/FM/cassette player installers at one time or another, all of whom went looking for a power wire to tap into.
