so I have the factory stuff everything in place and want to go after market, I dont have the mach460 but there is like 3 connectors that look the same in the dash and an amp in there as well... I noticed the setup from the factory head unit to the cd player just below.. is there I hook up I can put in so I can run my ipod instead of the cd unit? does any1 have the wiring schematic for this crap?
