wires?

Hi, just bought a p71 crown vic 2001.... blah blah blah... Anyways i was taking apart the dash and i was curious to know what the previous fbi owner was doing with all these switches and wires...
Pictures 1-4 are located to the left of the speedometer and such... My question is, is this used for anything in particular? Perhaps to run tests errr something? ahaha i dont know...

This is also another funny thing, this is found right underneath the radio and it is a simple switch, i have no idea where the wire could of come from or what it could of been hooked up too.

Sorry i am not to great with this img thing, i tried it but bare with me.

The one below the headlight switch should be the Rear Window Defogger, and the one below the radio is the trunk release. If these switches (wires) you are talking about are IN ADDITION TO the abovementened switches, then you got me.
