    Hi everyone.

    I want to reinstall the stock radio in my Celica and unfortunately i didn't find the stock connector amongst the many spare parts included.

    1989 Celica GT-S ST162. Canada if that changes anything...

    P.S 1: No i don't expect or need the cassette tape to be functional. As soon as i test the unit to see if it's still alive, I'll modify it so it has an auxiliary 1/8" jack input.

    P.S 2: Car is all good so far by the way. Needs a clutch but nothing major. Loving it. The front windshield washer sprayers even fixed themselves! (Long shot i know haha. I suspect a bad contact.)

    Ok then does anyone have the connector for the stock radio or know where i could find one?
    Ebay? How is that connector called? What keywords should i use? Would that information be in either the Hayne's or Chilton manuals? I spotted that RockAuto still has them both.

    I might be wrong, but afaik, there is a standard for these connectors, so they should be the same in most of the cars.

    Thanks. I'll take the radio to the junkyard and try some connectors on it, maybe one will match.

    I found it! :D The connector from the 5th generation Tercel fits. It's only missing, as expected, the pins/wires for the antenna trigger.

    In case someone else attempts this someday i will add this bit of information.
    This is the wiring "diagram"* i used. It is correct.

    Next i will have news on this project wich turned unexpectedly, amazingly well as for the AUX input mod, this thing is going to look and feel as if the radio unit had been designed this way!

    Also i'll try to draw an actual PinOut for the radio/amp while it's still out of the car and I'm lucky to have the plug.

    I'll also take and post pictures of the AUX input mod.

    *They call it a diagram but i don't think that's the proper term is it?

    Edit: Text color turned out black when copy-pasted, was a pain to read. Added asterisk.

    I used any plug that fit the connector and added the pins and wiring. Alternatively, you can buy ready-made plugs for about $10 or so. Nice info you added, will be helpful for DIY'ers.
