Re: Aftermarket radio/CD install for '90 Miata?

Well as I said, my '91 did not come with a radio or wires for the seat
speakers. The plug for a radio was there, but no other wiring that came
back past the dash. When I put in a radio ( non-OEM ) I had to get a
plug to match and wire to the radio wires then add rear speaker wire and
disconect-plugs. The Clearwater spraker kit came with wires to run down
the back of the seats and I needed to add the connecting plugs.

It sounds like the later Miatas came with the wireing in place.
