Aha. The wiper motor stud looks right. The wire is the exact length to reach it while still going through a couple of wire loom tabs, and the bend in the wire follows the contour of the firewall behind that location.
I saw what you mentioned about the original wire scheme, but I would soooo shorten that wire and attach it to the blower motor stud right next to it.
Most of the ones I have seen go there, so it wouldn't be to out there.
