obd1, and obd2 ports

[87_GT]

i have a 1995 gts and i have an obd1 port under my hood, and a obd2 port undermy dash. what is up with that? is do a lot of out cars have this?

the port under the dash looks like an obd2 port but it is actually obd1, obd2 didn't start until 1996. the data port under the hood behind the passenger side shock tower is a ford 1a connection.

oo really, well that makes more sense. what is a ford 1a connection?

 

[95cobradude]

the name of the connector to hook up the snap on scanner to a pre 96 ford vehicle is a ford 1a connector but basically that is where all the data and codes would be gathered from, not under the dash.

94-95's have OBD-I and OBD-II ports. The V6's are OBD-II so both ports are present (they use the ALDL for OBD-II and we use the underhood one for OBD-I).

This is 100% correct. The dash is identical between all the 94-95 models, except for the instrument cluster of course. The connector is inactive on the GT and Cobra.

All 94-95 Mustangs originated on the same assembly line. So, the V6, GT and Cobra share the same wiring inside the car. At a later point, they diverged and each car became a V6, GT or Cobra. This was Ford's way of saving money, combining the assembly lines. In '96, Ford split the assembly lines and only installed the wiring necessary for each car. I guess they didn't save as much money as they thought.

87 GT you must have been reading my mind. I saw and was wondering the same thing too. Now I know. Peace.
