No apology needed Chris, perfectly reasonable question.

The depth of knowledge here is incredible - there are about five guys here who I’m convinced could assemble a Volvo from parts on boxes in the dark, on a ship in rough seas.

The next leg of the journey...

I've managed to remove ECM and TCM and the harness connector to the ECM receiver. I identified the wires coming from the throttle body harness and have taped each for future ease of location. However, with my trusty set of pin extractors I cannot for the life of me pull each wire from the connector shown in the image above. The image highlights two of the larger sockets verified with my multi-meter.

Does anyone know a trick that I'm missing extracting these wires? Clearly, my complete lack of auto electronics experience is hindering me more than a little.

Again, I appreciate the help. I'd be dead in the water without this site.

The tool compresses the locking tabs that keep the pin in the housing.
Look up into the housing for the locking tabs so you will know what your after.

1. Find the right extractor.
2. Push on the wire from the back side.
3. Insert extractor into the front side.
4. Pull pin out back side.
5. Remove extractor.

RHP - thanks for the directions. That will help. Any idea which extractor works on the pins I've highlighted? I've tried the dual pointy pin extractor tip of varying sizes and the single rectangular tip. The cylindrical ones don't seem right.

To remove those you need use a pin extractor with side to side pins. Not a tube shaped pin extractor.
