On this page you'll find the 60-pin PCM connector pinout for the 1990 3.8L V6 Ford Taurus and Mercury Sable (EEC-IV system).
The EEC-IV computer uses a 60-pin connector. On the wire side of the connector, you'll notice small raised (embossed) numbers; those numbers will help you match each circuit to its correct pin.
APPLIES TO: The PCM connector pinout applies only to the following vehicles:
- 3.8L V6 Ford Taurus: 1990.
- 3.8L V6 Mercury Sable: 1990.
