It sounds like you are going all the way back to the engine computer. I hate to admit it, but you may have a project that is better handled by replacing the harness. While they are real expensive to buy a new one, this is something the salvage yards have very little call for, so they are likely to not charge very much. You might offer them fifty bucks if they will remove for you the exact one you need. Fifty bucks is better than letting it be crushed when they get rid of the car. Also consider finding a pick-your-own-parts salvage yard. If you are anywhere between Ohio to southern Georgia, and now even in Texas and a few other states, do a search for "Pull-A-Part" and see if there is a yard near you. Their yards are very clean and well-organized. People are friendly and they have real good prices. You pay your buck, take your own tools, and you can spend all day there. That gives you the opportunity to see what it takes to get the old harness off, and if you want to go through that much work on your car.
The alternative is to find replacement connectors and splice them to the car's wires. Every auto parts store has a pile of books showing almost every connector for every car model. They come with about six inches of wire. The problems are this is the more expensive way to do it, and those wire colors rarely match the originals. Most factory wires are a solid color with a "tracer", meaning a stripe, of a different color. The replacement connectors usually come with generic solid-color wires. You just match up the locations, when you have the old connector you are removing. When you have just a bunch of wires hanging there, you are better off snipping your own replacements at the salvage yard. That way you will get the right connector for the application, with the same color wires. Then it is just a matter of splicing the wires together. Always solder them, and never use electrical tape to seal the splices. That will unravel into a gooey mess on a hot day. Use heat-shrink tubing with the hot-melt glue inside. That will seal out moisture.
