i'm trying to add a cd player to my mach 460 system (i have a '95 GT) and i want to add it in the empty slot below my mach cassette player. i went to circuit city and they sold me two harnesses but they are not enough/not the correct harnesses to do the job. i need part numbers for the proper metra harnesses (or another brand if you know of one) that will help me finish this project. i bought a pioneer head unit and want to retain the stock amp, speakers, etc. is it possible to wire the pioneer back to the casette player so the mach 460 still functions? or would it be easier to just swap head units? anyone that can give me some part numbers of the harnesses i need would be greatly appreciated...thanks everyone, especially if this is a worn out topic...i'm just frustrated beyond belief.
