If you really want to learn about your z go to eBay and buy you a CD that contains the repair manual. They are cheap. I have one for my 93z and it is great.
http://www.300zx-twinturbo.com/cgi-bin/manual.cgi look through the service manual.
You can find a repair CD on many of the auctions. I paid $10.00 bucks for mine.
On my '86, 300zx NA, the rocker switch on the console turns on the heated outside mirror (drivers side).
