Radio/ Int. Light Outage

I was attempting to install my new radio unit when the interior dome light and door lights went off and didn't come back on, I had the console pulled off and was yanking on the stereo wiring harness I think when it went off, now my old radio wont even work nor will the interior lights come on when the vehicle is on or off. I think something may have come loose in the live battery lead circuit that is on when the vehicle is off. I have a 1993 model Trooper that has been great but this is killing me! someone please help!
