The most common harness lacing pattern for most backplates has the webbing crossing the tank side of the plate at the top. If your plate has tank attachment hole under the webbing you need to make a matching hole in the webbing. (DSS plates do not require a hole, as the webbing slots are located to miss the tank mounting holes)
The easiest way I know of is a hot soldering iron, just melt a hole, no grommet needed. The loads on the webbing at this point are trivial. If you were to cut the webbing in half at this point you still could not pull the shoulder strap out of the plate due the double slots at the top of each shoulder strap.
Regarding slot finishing. If you need to deburr and radius harness slots I'd recommend buying a couple sheets of "crocus cloth" It's like sand paper, but uses a cloth backing instead of paper. 120-180 grit.
Tear the cloth into strips and use them "shoeshine" style to buff out the slots. Narrow strips for the slot ends, ~1" wide for the slot sides. Clamping the plate to a bench helps too.
