The 1994 4.0L V6 Ford Explorer/Ranger is equipped with the E.E.C IV system and so its computer has 60 pins.
Ford Eec-iv Wiring Diagram
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.
The EL EEC-V Wiring connector is the Standard Ford 60 Pin Connector, as used on the XF 4.1 EFI, EBII 4.0, and ED 4.0 EEC modules. Please Note that Pin 1. Is located on the lower Row, Far Left, when the wiring connector is facing somewhere pretty. The EL 4.0i EEC-V Module has the following features, 1. (, 05:35 PM) Gary M.

Safety Precautions
Here are some very important safety precautions when testing the wires coming out of the 60 pin PCM connector.
![Ford Ford](/uploads/1/1/8/7/118765603/266077636.gif)
- 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 4.0L Explorer or 4.0L Ford Ranger.
- 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.
- You should use a wire piercing probe and probe the wire a few inches away from the connector.
- You should never disconnect any of the PCM connectors without first disconnecting the battery negative terminal.
