hello evryone, 1st I would like to say I have checked the search tab and ended with no results.
I have an 83 fb (basemodel) and replaced my head unit awile ago. I have purchased a stock working power antena and CANNOT find the plug that plugs the antena into it. Doesnt all of our cars come prewired fully loaded or not with this plug, does anyone know were that wire/plugs can be found I have searched all over and connot find it only the wiper plug (wich I dont have a rear wiper). also does anybody know or can point me how, what to do to set this up. I am in the process of toucjing up some loose ends before the car goes into the shop for body and paint. any help is apreciated

 

The plug for the antenna should be behind the right rear speaker panel trim.

 

thats the 1st place I checked and checked again and still no plug. its driving me crazy, do you think that mazda made that as an option only? thanks Doc for getting responding so quickly

 

It should be there. I put in an automatic antenna when I had my S model and the plug was there. It may be behind the right rear speaker. But all the Fb's are wired for all accessories.

 

I am going to check again in the morining. thanks
again

 

call me crazy but its no were to be found

 

I just ran new wires to the radio for mine - took less than 15 min. I purchased a parts america special

 

I know Doc,trochoid, & wacky are going to get angry at what I am about to say (I should be using the wiring daigram that is availble to all members on this forum)but does anyone have a qucik wring diagram that I can understand on how to wire the aftermarkt radio.
also include relays if needed thanks, and I owe you big time.

 

Huum...
Almost all new aftermarket radios have a yellow (may be diff) wire that is used to signal the antenna. Provide constant power to the antenna and this signal to the input on the antenna and you are good to go.

 

so their are no relasy wires other than the wire i have to run form the radio to the antenna, nothing, not even form the battery? if so thank you

 

Well I have to be careful with my answer - I used an after market unit from parts america that had a relay built in to the antenna The interface is a power on signal that drives antenna up, take power away and it drops down. It is very simple on the aftermarket.

If I remember correctly (none of mine were factory), the factory one used a separate relay (it has been 20 years) and I think you said you are using a factory one. Generally, the relay is used to swap power and ground to the motor to control its direction.

Section G of the 81 electrical manual has the relay and schematic...

Here is the page to which I was referring...

 

Iirc, the stock antenna powers up, the the relay switches so it can power down. I have found that the S models were missing some af the wiring for options, i.e., power window harness in the doors, but I belive all of them had power antennna.

I had a friend that had some odd wiring in his 1st gen. If you turned the dome light to the off position, it shut off the radio and powered down the antenna. Go figure, lol.

Does it appear that you have have the wiring to plug into a relay, if so, somone should have a relay from a parts car.
