Audio system, and door lock question?

[1991fordexploder]

my X came W/O Factory sub and extra amp, and W/O rear door lock button, should all of the wiring be in my X? i pulled the D/Lock button out of a junk X. Should it hook right up, same question for the sub.

If yours has the Premium system with an amplifier for the 4 speakers, but no sub, the sub for a 91-94 JBL system usually just plugs right in with the existing connectors.

4 doors with power locks from the factory all had lock/unlock switches, unless they were special use goverment or law enforcement vehicles or something. I'd suspect the wiring is there, and the any lock-less switches can be swapped out.

just get an aftermarket sub amp combo. The stock won't do much.
