There are too many plugs for 1/2" holes (N) and not enough for 9/16" holes (F).
The center hole in the grommet for the main harness is too big. Use a short section of 1/2" heater hose as a bushing.
Plug E and grommet J don’t appear to fit anything.
As an aside, the "L" plugs in this kit are a perfect fit as the impact cushion for the Coupe exterior door handle.
