Ok im gonna buy a 94 Mustang probably today. and it has a check engine light on and the guy says he cant find the Port. he looked everywhere under the hood and under the dash where on earth is this port?
Well he obviously didn't look good enough. The port is right under the drivers side dash. It's in the bottom right hand corner near the center dash bezel. You'll see it sticking out on the outside of the radio mounting bracket. Can't miss it.
