The power plug should be the same.  Differences would be Stereo versus non-stereo, 4 speaker, 2 speaker or single speaker in the center of the dash for a mono AM or AM-FM.

chevyman, what colors are the wires in the old harness and how many, and what are colors of wire in new harness and wire count
I wired a front and rear set of speakers to both the early and late harnesses to bench test radios and am currently rewiring my truck radio harness from scratch
