I’m switching out my radio. I have everything connected and the new radio powers on but no sound comes out. What do I do or maybe I have the wiring wrong.

Hi,

I attached a copy of the wiring schematic for the base radio on this vehicle. I had to cut the schematic in two to make it readable.

If you look at the pics, I circled each speaker. The wire color for each speaker is indicated in the schematic. Make sure you are connecting the new radio's output to the correct wires.

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
