Below, you're going to find the 60-pin connector pin-out of the EEC-IV fuel injection computer for the 1991-1992 3.0L V6 Ford Taurus and Mercury Sable.
The EEC-IV PCM has a 60 pin connector and on the back side of the connector (wire side) are embossed a few numbers to further aid you in correctly identifying the pins (circuits).
APPLIES TO: The PCM connector pinout applies only to the following Overhead Valve (OHV) non-DOHC and non-Flex Fuel vehicles:
- 3.0L V6 (OHV) Ford Taurus: 1991, 1992.
- 3.0L V6 (OHV) Mercury Sable: 1991, 1992.
