We investigate the behavior of the four terminal resistance in an interacting quantum wire described by a Luttinger liquid with an applied bias voltage V and coupled totwo voltage probes. We extend previous results, obtained for very weakly coupled contacts, to the case in which the effects of the probes become non trivially correlated.
