1996 Toyota T100 SR5 Standard Base Theft Deterrent System?

Recently bought a 1996 Toyota T100.  On the windows there are stickers that
say Theft Deterrent Protected.  They're Toyota Factory stickers.  There is an
LED to the left side of the steering wheel.  There is a very tiny toggle switch
under the steering column and under the cabin fuse box with two white and
black leads and a female connector, but the wires aren't attached to anything.  
What gives?  Did they disarm this factory alarm and why? And when I bought
the truck I was given a regular key, and the dealership says I can get keyless
entry.  Any help would be appreciated
