i need to ge the code off of my pcm.... where exactly is it located and where could i get the code? its a 99 mustang

 

If I understand correctly you have a CEL code and you can get it read at autozone for free.

 

are u sure thats it? because i really dont know what i am looking for

 

Your trying to buy a SCT, correct? And you looking for the computer code that you need to get it. If your sitting in the passenger seat it will be on the right side of your feet, just pull the carpet back and it should be on a white rectangular sticker. Atleast mine was.
