Default Power antenna upgrade -1997 miata

For anyone who might be wondering....I hooked it up wrong.

If you decide to go for the power antenna on a car that did not have
it(look for a rubber plug where the drain tube connects near the
battery....that would be pretty indicative of a car that did not have
it...) you need two things. The fuse block, it has two fuses in it,
one for the antenna and one for the defroster. For cars that did have
one or the other, this block won't be on the car. Instead you can find
the fuse in the fuse block under the dash, after you fold yourself up
to get your head under there.

Anyway, the 'fuse block' goes on the connector with all four wires
populated. That was my biggest mistake. Hook it up wrong and nothing
works. Nothing starts on fire either, which is a good thing.

The power antenna, despite the fact that the connector has four pins,
and four wires that go into the motor(at least on mine..1997 NA), only
TWO of those wires actually go anywhere. The other two, at least on my
antenna motor, dead-end on the PCB inside the clear plastic box. On
the plug that hooks up to the antenna motor one lead has 12V constant,
the other one has 12V when the radio is on and the antenna signal is
being sent. The antenna motor receives its ground connection via the
body of the car. +12V on both wires = Antenna up. +12V on one wire =
Antenna down. There's a relay and a switch on the back that stops the
motor when the antenna is fully extended/retracted by way of a clutch
assembly.

Anyway such ends the story. It works like a champ now.
