I am trying to wire up my aftermarket stereo in my blazer but i have no clue what any of the wire colors mean this is a 94 s-10 type tahoe LTS if anyone might know please post somthin to help that would really be cool

 

Find your nearest aftermarket auto stereo dealer and ask them for a wiring harness. Takes all the guess work out. Just plug one end into the factory wiring harness and the other end into the aftermarket stereo. Well worth the couple bucks they want for em.
