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