    Cut/disconnected wires under dash

    I found two pairs of wires under the dash of my 1997 TJ. One pair on driver side, one pair on passenger side. I tried hooking up a voltmeter and a speaker, but neither showed a signal. And the footwell lights have a separate connection. Does anybody know what these are for?
