Jim - Yes, that's pretty much how respooling works.
The most odd aspect was that this was wiring already in a wiring harness, taken from a box with the appropriate wiring harness labeling. The FUS Rep wanted to see our drawings to verify the design of the harness, which is normal, but specifically wanted to verify the type of wire used. For as much as drawings are all they have to work with (if they ignore surface markings), this is at least another level removed from the actual harness build. Ah, well, there were no problems after the drawing review, so I have no reason to complain. It just seems that trusting the drawing and not trusting the surface markings on the wire are somewhat contradictory. Regards, Peter L.
