    The Toyota Supra Community for all Supra generations

    Owners of the fifth generation Toyota Supra are thrilled about that car

    In July 1993, the fourth and so far last generation of the Supra came on the market. Internationally, this type is called " Supra MKIV ".

    In early 1986, the third generation of the Supra was introduced. It is also the first that has not been marketed with the suffix Celica.

    The second generation was presented in the fall of 1981 and had a completely independent drive with the new (170 hp) 6-cylinder engines.

    The first Supra built from spring 1978 to summer 1981 was still offered as a top version of the Celica first in Japan and later in the United States.

    Hello, sorry for English post but I believe this document only exists in German.

    Does anyone have better image of the connector and the pin data?

    I'm installing OUT-TEMP clock(uhr) to JDM Supra.


    Here is all the documents I have, the connecting looks good but I can't see what pins to connect because the image for that is too blurry.

    Can someone take better picture of the RIGHT PAGE? :)


    Thank you.


    Hi, i've made this photo. I will try to find the big version on my smartphone or will make a new one tomorrow.

    Maybe this thread will help you, too

    Hi thanks, it seems to connect directly to A / C Amplifier, I'm guessing that part is same in every car?

    So it uses the original AMBIENT temp sensor.


    Edit: Yes, they both use same part! 88650-14270

    Can you find A/C Amplifier (KLIMAANLAGE VERSTÄRKER) output from your german wiring manual aswell?

    That would be needed so I know where to connect the TEMP pin. :)

    Check out manuals.

    Ah yes, it goes to the engine room ambient temp sensor, but now I need to figure where it goes from there so I can get it directly from A/C amp.

    Ahh ok. So i have to look into my euspec wiring book. Will check it tomorrow ?
    Thank you, it's very hard to find EU spec wiring book data anywhere!



    I think I found it, made this diagram! :)

    Yes, the diagram is the same. I ve made you a photo of the right page, too

    When I press the OUT-TEMP button, the display shows nothing like it's not on.

    Any ideas? Clock side works normally.


    The A18 on EU spec should be G19 on my end. I noticed that I have 2 less wires going to the A/C amplifier compared to EU-Spec, I want to know what those wires are.

    This is the same as the US Spec cars, they have two less wires as they don´t have the outside temperature feature.  One wire goes to the Temp Controller which get´s it´s reading through the A.C. temperature sensor "Pin 1 on the C12 connector" and the other is the "Pin 2 10A Gauge easy to wire in."  As for the wiring on the A.C. Controller EU I haven´t looked into.  Both connectors A18 and G19 should be the same.  Maybe one single wire has been changed around for some reason.
