There are a lot of features that were in the donor car that I won't be using in the kit, so I am just tripping wire out that is related to those feature. In this example, anti-lock brakes. Nope, no driver aids in the kit car. This is the connector that plugged into the ABS unit, and I don't wat it flopping around in the kit, so it's time to diet it.
Oddly, this reminded me a lot of chasing network cables through a crowded wiring closet. I guess my time in IT has some real-world applications after all.
When you get to the other end of the wire, cut it off there, too.
Then identify and diet the next unneeded plug.
You may note a couple of things in the background of this pic - first, my hands are filthy; and second, the orange bucket half-full of trash. Both of these result from having to remove a lot of electric tape and wire loom from the bundled harness. The adhesive on the tape, after years in the donor car, turns to goo that gets all over everything and is challenging to wash off.
