We have brick here, but working on such an Adobe house should give you a feeling what it's like to be an electrician in Austria or Germany. Ridging the plaster to lay either flexible PVC conduit or NM style cable is everyday practice. Austrians prefer conduit, Germans seem to love cable. I grew up with conduit.
Typical Adobe is _not_ fired, only the top coat prevents it from being washed away. I know a guy here in Austria who tore down his adobe wall with the garden hose... his barn (leaking roof) looks like half-molten chocolate!
