I had my car totaled but got to salvage my Pioneer AVM P8000R and my AVH P7480DVD. I was able to take my head unit out and disconnect it from the harness. At the brain's end that was under my seat I was able to disconnect the wires connecting it but could not take the wires with me. So basically I have the two units and no wires. Where do I buy the wires for them? Can i just take the two units to an install place and they can find the wires for me?
