I can't live with the engine whine anymore. Happens no matter what source I am playing. Did not start until after I had the VSS wire hooked up. Taking it back to the installer this week. Any suggestions on what to tell them? (Other than get the thing fixed)

Let me know what you find out

Try a power filter on the switched or constant 12v sources and see if that helps.

Add the noise filter, and have the installer twist the power/ground wires(make them look like a pretzel). Also--make sure they're using the ground stud under the driver side kick panel--using the dash carrier for a ground isn't ideal.
