Car Stereo Connector for 1994 - Up Select Vehicles. This Premium Sound Car Stereo Connector connects after-market stereos to factory wiring systems and eliminates the need to cut into the existing harness.
Used it on a 2000 Mustang w/ premium sound, not Mach 460, only needed the flat gray plug, wired it to my HU power wires, needed the other plug to bypass the amp,,,,, Much easier than cutting/splicing the wires in the dash, highly recommended! The other plugs would be useful if you don't want to bypass the factory amp.
