I'm still discovering things on my recently purchased '96 Aerostar. One thing that has me baffled is a rather small (perhaps 2"X3/4") black device with the markings of Auto Guard Security system. There is, what appears to be, a key-card inserted into the face. I tried to extract it but was unsuccessful. Is this something that Ford had as an add-on or is it the product of some TV sales offering? The harness leading from the back is quite stout so it must have a number 0f conductors. Incidently, it's located right next to the OBD port.
I was unable to find out anything on line so would greatly appreciate any information about it
