  We propose the simplest TeV-scale scotogenic extension of the original 3-3-1
theory, where dark matter stability is linked to the Dirac nature of neutrinos,
which results from an unbroken $B-L$ gauge symmetry. The new gauge bosons get
masses through the interplay of spontaneous symmetry breaking \`a la Higgs and
the Stueckelberg mechanism.
