  The conducting properties of the pressure-induced, layered organic
superconductor (BEDT-TTF)_3Cl_2.2H_20 have been studied at 13.5 and 14.0 kbar
using low temperatures, high magnetic fields and two-axis rotation. An upper
critical field that is significantly larger than that expected from the Pauli
paramagnetic limit is observed when the field is applied parallel to the
conducting layers. The angle dependent magnetoresistance suggests incoherent
transport between the conducting layers at both pressures and the observed
negative magnetoresistance at 13.5 kbar can be explained by considering
Anderson localization within the layers. Further application of pressure
destroys the effects of localization.
