This is actually correct.
1. Look for a white or light grey plastic connector with two metal prongs inside that is NOT plugged into anything. This connector is located in the trunk behind the left-hang side trim panel. It will be taped to the wiring harness that leads to the tail lights but closer to the wheel well.
2. This connector verifies a keyless entry system is installed.
I have a 95, I went to the ford dealership and asked if I had keyless entry and he was like give me your key and I will tell you, he went out and did the try for the 2000+ mustangs, (turn the ignition 8 times) and it didn't do anything, obviously it is a 1995, and told me I didn't.
I just walked outside and did this and it worked, now I'm going to buy a remote.
I can get you pictures if needed.
