1994 Ford 3.0L Ranger PCM Pin Out Chart

The 1994 3.0L V6 Ford Ranger is equipped with the E.E.C IV system and so its computer has 60 pins.

Whether you're tracing down an electrical short or testing one of the input/output components of the PCM, pinout charts come in handy. Below you'll find the description of each pin.

Safety Precautions

Here are some very important safety precautions when testing the wires coming out of the 60 pin PCM connector.

1. If one or any of the wires on your Ford pickup DO NOT match the color stated in the pin out charts, then you should not use the pin out charts in this article. Why? Because this is the clearest indication that these ARE NOT the connector pin out charts for your particular Ford 3.0L Ranger.
2. Never probe the front of the connector.
   • You should use a wire piercing probe and probe the wire a few inches away from the connector.
     • To see what this tool looks like: Wire Piercing Probe.
   • You should use a back-probe.
3. You should never disconnect any of the PCM connectors without first disconnecting the battery negative (-) terminal.
