The EEC-V powertrain control module (PCM) has a 104 pin connector. To aid you in correctly identifying the connector pins, the back side of the connector (wire side) is embossed with a few numbers.
APPLIES TO: The PCM connector pinout applies on to the following vehicles:
- Ford E150 4.2L V6: 1999.
- Ford E250 4.2L V6: 1999.
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.

Safety Precautions
Here are some very important safety precautions when testing the wires coming out of the 104 pin PCM connector.
- 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 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: Goupchn 4mm Banana to Banana Plug Test Leads Kit (Amazon affiliate link)..
- 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.
