Well...77-80 is one style and 81-up is another. You need a new style harness since those are newer doors. The fuse panel only requires an IGN source and Battery source. Window circuit will also need a chassis ground underdash. So, if you want to save a little $$$, you need to pull a complete harness from an 81-up Suburban or crewcab-then install it all as-is into your truck. If you don't have power in it now, you need to drill for cab-door grommets too-both inside and outside. I can supply you with a complete hybridbharness just for your application for a clean stock appearance but otherwise you'll need to source it all from a newer truck....trust me those are your two options.
