Would it possible/feasible to swap the required harness and speakers/stereo from a late model wrecked LS truck into my '92 regular cab truck...I was thinking earlier about using a 2003 trailblazer stereo (the one in it was NO comparison in sound quality!) as a donor but heard the harness/system is totally different. But I'm thinking if I can just swap harness and computer too, this might make me a very happy camper, without breaking the bank with custom stereo equipment.

There just aren't many options out there for stereo for this rig otherwise, so I'm trying to be creative.
