i need some advice on wiring an aftermarket stereo on my trailblazer..i wanna upgrade my truck with right now an amp,woofer and a new headunit...but here is the question do i really need all the onstar or boss equitment stuff?...i already lastnight started wiring my amp im almost done doing that.. i already took the dash off also the stereo...but i cant seem to find just the wiring harness without all that boss stuff...i dont care about the chime or anything like that...anyone know a place were i could get the wiring harness without the onstar or the boss..just plain wiring harness..ill take any advice also..thanks!
