Here's the EEC-IV 60-pin PCM pin-out for the 1991-1992 Taurus/Sable with the 3.8L V6 engine.
This PCM uses a 60-terminal connector. On the back (wire side), Ford molded tiny identification numbers on the connector so you can confirm pin locations while tracing circuits.
APPLIES TO: The PCM connector pinout applies only to the following vehicles:
- 3.8L V6 Ford Taurus: 1991, 1992.
- 3.8L V6 Mercury Sable: 1991, 1992.
