putting the diag port under the drives side dash was part of the OBDII standards that became mandatory in 96.

yours will be in the drivers side fender well under the hood. between the innter fender well and the brake booster/master cylinder. there should be a protective cap on the end. if not, good luck.

autozone and other parts store sell a code reader for ford EEC systems.
