I use a syms like http://turkos.aspodata.se/git/openhw/share/gschem/mechanical1.sym http://turkos.aspodata.se/git/openhw/share/gschem/radiometrix_rx2a.sym and footprints like http://turkos.aspodata.se/git/openhw/share/pcb/_mechanical/fibox_tempo_TA191209T_4p.fp http://turkos.aspodata.se/git/openhw/share/pcb/_modules/radiometrix_rx2a_laying.fp where the chassi pins have the same pin number.
