u said the rear+rspeaker is yellow i dont hav any yellow wires wat could b the other colors
I couldn't find anything for the Trailblazer. I did find these colors for the Blazer. They should be the same. LR Speaker (pos - brown) (neg - yellow) , RR Speaker (pos - dark. blue)( neg - light blue)
can it be checked with a VOM like plus to ground from one wire at a time?
