If you dismantle it a bit more you will find the perfect grommets

Can't see too well from the photos. I'm looking to do something similar for an electronic oil gauge. There must be a grommet that passes through wiring harnesses, although sometimes they have a boot over the wiring conduit. Likely a case of unpicking one of those or finding a blanking plug.

This might provide some clues:
