I just change out my stock radio in my 02' trailblazer. I could not locate the proper wiring harness so I cut out the stock one and hard wired in the new Alpine harness. It all works great except I now have no ICP lights or Climate control lights. All of the gauges on the IPC/DIC work fine I just have no illumination. There was a orange wire and a black wire left after I put in the aftermarket harness. Can anyone help me- Its hard to go the speed limit when its dark.
