How do you take out the back seat in a 2002 SC? Not the part you sit on but the back part against the back of the cab.

 

If SC means SuperCab then look at the rear cab wall under the seats. Using a mirror comes in handy for this. You will see part of the seat back frame in the shape of a U hooked into a latch on the cab wall, one on each side. Just pull on the latches while pushing upward on the seat back.

If SC means SuperCrew then it might be similar but I don't have one of those in the garage to check.
