The Mach 460 is very easy to make work with an aftermarket stereo and here is what you do and buy. Go to your local Best Buy and pick up these parts: PSI2 Factory amp intergrator, Ford amp integrator harness, and a multi purpose pocket- $39.99, $15.99, $15.99
The Pocket takes the place of the fact. cd player. The PSI2 is a unit that wires into your speaker wires and makes it compatible with all aftermarket radios, and you will never have problems with it! And the harness plugs into your factory wiring so there is no guessing and or hacking your wires.
I am a manager at Best Buy and have been professionally installing stereo's for 7 years! Email me your questoins.
