I also made up a cable a few years ago from an old ABS plug and socket, some speaker wire and a bit of chocblock. The original idea was to use it as an extension cable so that any ABS sensor could be plugged into the OSF and the speedometer used as a diagnostic.
Here it is being used to check a hub before fitting to the car:

Mike -- how did the sensor move further away from the reluctor ring which is fixed in the hub? - The sensors are up tight against the hub backplate and held in with an 8mm bolt. Unless you had a bang on the backplate, buckling it away from the hub somehow? I'm going to check both these distances on both rear backplates to see if there is any variance, but both looked normal on the last inspection.

Very easy to damage the magnetic reluctor rings if drilling out old ABS sensors, or get a fault as I did when I replaced first the bearing due to it wearing out, and then a couple of years later, the sensor when it packed up, with non original parts.
There was no damage to the hub or backplate and no rust build up around the mounting, so likely the combination of the two aftermarket items needed a slightly smaller air gap to function correctly together.
As French Mike says: Measuring is knowing.
