Safety Precautions

Here are some very important safety precautions when testing the wires coming out of the 104 pin PCM connector.

  1. If one or any of the wires on your Ford van 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 Crown Vic/Grand Marquis.
  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.
    • You should use a back-probe.
  3. You should never disconnect any of the PCM connectors without first disconnecting the battery negative (-) terminal.
