The red plug is to connect it to a tape deck, so that it starts recording exactly when the needle is dropped, and to presumably stop when the tonearm returns.
The older components in the late 80s and early 90s were connected to each other with wires that controlled either the remote control for the components or the syncro edit functions when recording record to cassette or CD to cassette. Later models had sensors on each of the components for remote function and that reduced the amount of wiring instead of just using only the one sensor on the tuner. So they got rid of those connections for remote control.
I got lucky i bought a optumis its just like this one. When i got it i paid 15 dollars for it because it wasn't working. The problem was it would play 80 % of the record then it would make a non stop clicking sound then it would go back to its base. I thought i was going to go through hell to fix it. I took it all apart and found the problem some how the adapter to play 7" records was inside the player stopping the arm from going all the way acrossed i pulled that out and put it back together its been working fine no problems not bad for only 15 dollars if any one wants to know what model it was it was a lab-2250

The ground wire is to ground the cartridge to the preamp or amp chassis to eliminate hum.

The SL-J3 is a lot easier to take apart than the SL7. The SL7 also has a tiny motoring the covers break more easily.
