  We study a general Majorana junction, where N helical nanowires are connected
to a common s-wave superconductor proximity-inducing Majorana bound states in
the wires. The normal part of each wire (j=1,...,N) acts as connected lead,
where electrons can tunnel into the respective Majorana state \gamma_{A,j}. The
Majorana states at the other end, \gamma_{B,j}, are coupled to each other by an
arbitrary tunnel matrix. We examine the conditions for even-odd parity effects
in the tunnel conductance for various junction topologies.
