1992-1993 F150-F350 PCM 60 Pin Connector (4.9L, 5.0L, 5.8L Only)
The fuel injection computer (known in tech speak as the PCM = Powertrain Control Module) is located on the firewall (passenger side) of your Ford pickup.
The 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).
IMPORTANT: The illustration above and pin-out table below apply only to: 1992-1993 Ford pickup with 4.9L, 5.0L or 5.8L engine.

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