The O/D solenoid should be located externally on the transmission towards the rear on the left, disconnect the electrical connector and apply 12 volts directly to it and see if it makes a clicking noise, if not replace the solenoid, if it does then the problem is a little more complicated and could be related to the electrical wiring, the on/off switch or internal transmission problem.
AnswerI don't have any online information for this model supra so I tried to answer your question from memory but it seems that didn't help, I will look tomorrow if there is any printed information still available for the 82 and then get back to you.
I do not have a repair manual available for this model but I did find a wiring diagram and it shows that there is a single black wire for the overdrive solenoid.
