can't crank with key

Hi Ross,I had the same problem with my 66 Dart.It was in the bulkhead.I had read a link were they pulled the connectors out,drilled through(opening up for wire)and ran a positive wire through to the positive wire for ignition.It worked for me.My bulkhead was very corrosive in this area from PO cutting wires and jumping at the starter relay.Hope this helps?You could have other problems?Do you have power running with the key in run position?This solution runs direct power to your ign.
