2004 Dodge Ram Radio, locks, lights

The radio will not turn on. The locks only work when the ignition is on, door switch or remote. THe dome lights don't come on when you open the door and the headlights do not work unless the ignition is on. To me this would rule out fuses. The radio fuse is fine I checked it because the radio is the first problem i discovered. Recently had the bed replaced and frame starightened. Everything worked fine before the repair. Any good ideas where to look first?
Thanks!
