OK, I have a 97 stock head unit w/ 6 disc changer that my buddy just bought from me for his mustang (1985). The 6 disc changer has a wire bundle I unearthed and disconnected from underneath the passenger dash (it was a plug). From there, the wires branch off in many different directions and go to god knows where under the dash...here's the question: Is there a wire kit I can buy to connect the stock head unit straight to the 6 disc changer? Any info is helpfull. Thank's in advance

 

I don't know about finding extra cables for sale, but how is your buddy going to install that deck into his mustang. Those are DIN openings???
