EEC-V powertrain control module (PCM) has a 104-pin connector and in this page, you'll find the circuit description of each of those pins.
If you take a look at the backside (wire side) of the EEC-V PCM's 104-pin connector, you're going to see that there are some numbers embossed on the connector itself, and these numbers will help you correctly identify the pins you need to test.
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: 1999.
- 3.0L V6 (OHV) Mercury Sable: 1999.
