Is conduit required for wiring in a detached garage, or can the wire be run
to the outlet boxes in NM cable? I have exposed 2x4's with no drywall. Can
someone site a code reference? I am planning to add some additional wiring
to my garage and would like to do it correctly. I had seen something in an
old post about protecting wiring below 75".

National Electrical Code, Article 334. NM is fine in a detached garage. When
running it perpendicular to the studs, drill holes in the studs and feed the
cable through the holes. When running parallel to the studs, staple it to the
face of the studs (the wide side), not the edge. No need to put it in conduit.
