I have the same model year as yours, but that does not really matter. If you go to the back of your Haynes manual, the wiring color codes are spelled out for you specific to your car, It is possible that a new or rebuilt starter can be stuck (clearances on starter gear/and shaft) or that you somehow bolted it in slightly askew and it is stuck or cannot move properly. Spot check the ring gear teeth by looking through the starter hole to see if they are o.k. and that the gear on the starter seems correct. Also, look around and check and make sure the ground strap is good (motor to body) or any ground for that matter
Sometimes, if a motor or starter motor is in a locked rotor condition this will cause a heat rise. It might be a good idea to remove it and energize it with jumper cables from the battery-- (a bench test) to verify actuation. (spin) Then wipe the grease of the leads (so you can read your color code) and carefully connect them to the terminals as the wiring diagram tells you in the Haynes manual.

OK, There should not be a "Tan" wire there. It is probably the "Red" or "Orange" wire that has faded real bad and just looks tan. It goes on the same post as the large black battery cable. It should be a 10 gauge wire. The other end of that wire goes to the "BAT" terminal on the alternator. (in case you want to check and make sure) The smaller black wires should be ground wires, They will attach to the transmission housing. Usually, there is a special bolt with a stud made on the end of it and a nut that secures the wires. As you said, the purple wire goes to the small post on the starter solenoid.
