This is true. We save all (well, a lot) of the harnesses we remove. Sometimes you just need to harvest that one connector, or you need a few wires with pins to splice in. Very convenient to have.Not all connector bodies are serviced separately. In fact it is more common to find them not serviced. The workaround (from the factory wire repair manual by the way) is to use two avaliable mating connectors that fit the same terminals and have the same number or greater cavities.
