ABS harness ground and mount location

I am going over old service recommendations (PO) of my 98 S4 and the shop had mentioned:
"Replace ABS harness ground and mount (driver's side)"

Where are these located? does anybody have a picture?

Also Lower bell housing insulation form? what is that?
Thanks

See below for rear. Bolt centered in pic is the ground lug’s bolt. The ‘mount’ is the wheel bearing carrier. On the front it’s the wheel spindle. The harnesses are grounded at both ends. The ‘other’ ends are the chassis. B.S. note to replace the ‘mounts’. Grounds can be cleaned.

Thank you so much Dave. I see the wheel bearing carrier but not sure which one is the ground lug’s bolt?

It is almost exactly in the center of the picture. 8mm-head bolt. Look between the rear wheel bearing and the ABS harness barrel connector. Or, follow the small ground wire that comes out of the top of the tan-colored barrel connector on the right side of the wheel bearing. It goes up and then loops back down across the ABS harness and fastens to wheel carrier. Sorry about the picture. It's the best one I had at hand.
