Default Power antenna upgrade -1997 miata

All,

I have what I beleive is a good used power antenna motor from a 1996
miata. I bought a new mast for it, but I cannot get it to go up when
the radio turns on. I don't have a wiring diagram so maybe someone can
help me. I have a 4 wire plug on the motor itself, with the following
wires, Blue/red stripe - Tied to B+ with the plug in the car, Green/
white stripe - also Tied to B+ with the plug in the car. Blue/white
stripe, I don't see any voltage here, radio on or off. Black/yellow
stripe,no power here, either.

This car did not come with a power antenna, there was a rubber plug in
the hole for the drain tube, and there were two 4 pin square
connectors not plugged in to anything in the engine bay. The one
closest to the battery has tobe the one for the antenna, and the motor
does run briefly if I plug it in to this plug. The other one is for
that little 'fuse block', which I do have, but only two positions are
populated on that plug. The pin that lines up with the "Antenna" 10
amp fuse gets b+ when the radio turns on, but it goes nowhere, as the
other side of that fuse has no wire(?) I thought the power antenna
upgrade was a plug and play? Do you have to run a wire from the little
fuse block over to the antenna motor to make it work? It sure seems
like the signal to "Go UP!" is not making it to the antenna and I
don't know which pin the "Go UP!" signal is supposed to tie into.

Anyone know what I am missing or have a copy of the 1997 wiring manual
available for download somewhere?

Thanks,
Chris

I looked in Rod's but couldn't find anything about it. But I recently
replaced the non-power antenna in my '95 and noticed the power antenna
connector there so they are obviously wired for the option regardless if
it came with the car or not. The only thing that came to mind about
your dilemma is if you have the factory radio or not. If you have an
aftermarket radio it is possible that the lead for the power antenna was
not wired to the new radio harness and that would make it appear to be
'dead.'

first check the simple stuff

- is there a fuse blown, either at the unit of in the fuse block.
- is there power getting to the plug
- put power 12v directly to the unit, does it work?

i seem to remember a similar situation here and finally discovered
you have to ground the unit, (ie touch it to the body-doh!), before
it will work,

if all that fails, i will look up the wire diagram in my factory
manual for you.

also, if the top threads are good and you can not get get it to work,
i may be interested in buying the "bad" unit from you as mine works
but the top threads are shot.

cc me at ( pm icaza gmail com) no spaces, with @ and . in the right
places
lemme know,
peter

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.

from the factory with a manual antenna., the previous owner installed a
factory mazda power antenna,, It goes up when I turn on the ignition key. and
