I just junked my 1990 Mazda 929S, and took out the radio.
Goodgawd, I've never seen so many wires!!
In my car, there were one or two relays associated with the antenna,
switched by the radio--one for up, the other for down. I think the relays
are interconnected so that each one cuts itself out with a limiting switch,
and "prepares" the other--a kind of flip-flop.
The OP may be able to sleuth these out with a VOM. The actual antenna wire
should be connected to the chassis--I think. And possibly one directly to
The Mazda service center told me to come by to see their mazda mechanic, who
woulda done a look-see manual check for free, mebbe photocopy a page or two,
but it wasn't necessary, as ultimately the radio didn't work out.
Try mazda service in your area, might not bang you.
The Mitchell's manuals sound like a good idea, but the generic antenna may
be a little different, as well.
