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.'

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. :)
