Maybe it's grounded somewhere? That's a guess though.

Fords are notorious for either having a poor radio ground or a negative ground which both induce noise into your system. I would recommend bypassing the factory ground and (using a multi-meter) find a better place to run a new ground with proper hardware. This should help.
