Replaced head unit lost key  fob.?

I replaced my head unit in my 2003 Dodge ram. Apparently I did something wrong because I lost the key fob and the dome lights and the radio doesn't work. I checked fuses and the wires, but nothing seems wrong. Any thoughts?

    A key has to be turned to ACC or ON for the radio to work.  So start getting a key fob first.  If the fob is separate from the key, pull the head unit, get a test light and check for power at the fuse with key in ACC..  Check for power and ground at the head unit connector with the key in ACC.  it is very likely a ground issue common to older vehicles.
