Oh wow I had the same question a few hours ago. I assumed they were for another model supra, Im not sure what youre driving but I thought maybe they were for the turbo/automatic model or something like that. Theres an extra plug like that behind the speedo too. I assume that too is for the turbo model for the boost guage.

The black plug looks like the plug that hooks up to the HAC sensor. (Mounts by the glove box hinge).

The bigger white plug looks like the plug that hooks up to your dash harness, and I have no idea what the smaller white plug is for.
