does anyone have a wiring diagram or can tell me which wires are for the speakers and the 12v IGN wire for the factory head unit. i am installing my sub and need to install my converter and i can't find a diagram.

 

Howdy! I'm putting my system from my old 99 Mustang in my 02 S-crew FX4, so I'm looking at the wiring harness for the new headunit:

12V Ignition (Accessory) : RED

Right Front + : Gray
Right Front - : Gray w/ Black stripe

Left Front + : White
Left Front - : White w/ Black stripe

Right Rear + : Purple
Right Rear - : Purple w/ Black stripe

Left Rear + : Green
Left Rear - : Green w/ Black stripe

I hope this helps you out!
