I'am in the process of adding a aftermarket headunit to my hhr. I been having problems with getting the right wire harness for the job. I have purchased two already from best buy and they still can't seem to get me the right one. Can someone help me out on what is the right one to use!!

you can catch accesory in the large harness below the fuse box. it is a heavy guage Pink (10g or 12g) wire. some here say that wire doesnt exist, i say they have no clue what they are doing and probably good idea they dont use it.

so is there a wire harness out for this job or am i resorting to hard wiring it?

I think it was said in other posts, but since he has the base system, the wiring will be different. No line outs, antenna, amp trigger, maybe more differences. Probably a different harness.
