WIRE COLOR LEGEND: You can find the wire color legend here: PCM Connector Pinout Wire Color Legend.

PCM Connector Pinouts: The following PCM connector pinouts are available:

PCM Connector Pinout Wire Color Legend

  • BLK = Black
  • BLU = Blue
  • BRN = Brown
  • GRN = Green
  • GRY = Grey
  • ORG = Orange
  • PNK = Pink
  • PPL = Purple
  • RED = Red
  • TAN = Tan
  • VIO = VIO
  • WHT = White
  • YEL = Yellow

Some of the wires coming out of the PCM connector will have a stripe. With these wires, a slash is used to show both colors. For example:

  • BLK/WHT = Black with a white stripe.
  • ORG/BLK = Orange with a black stripe.

The first color is the main one, and the color after the slash is the stripe.

A few wire colors will have a 'LT' or a 'DK' before the color, like 'LT BLU' or 'DK BLU'. In this cases, the 'LT' refers to the word 'light' and the 'DK' refers to the word 'dark'. For example:

  • LT BLU = Light blue.
  • LT GRN/BLK = Light green with a black stripe.
  • DK GRN/WHT = Dark green with a white stripe.

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 pickup.
  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.
