Where can I Locate my Mustang’s Computer Code?

1987-2004 Mustangs:

The Mustang Computer Code on 1987 to 2004 Mustangs should be on the Passenger Side (RH) Door Jam on a rectangular white sticker. However, sometimes the sticker can come off. In that case, you will need to look under the Passenger Side Kick Panel on the actual computer to get your Mustang computer code. Below are two example images from our 1998 GT Mustang: one showing the RH kick panel removed with computer/wiring exposed, second showing a close up of the computer code = DBZ2

Please Note: the code can be located anywhere on the silver box, not just on the top as shown in the example.
