As a slight aside, I fitted an electric bonnet release as a primary system. I shortened the cable for the manual release and it's hidden in the cabin as the backup system.
It wasn't too difficult to fit the electric release, ( just an electric boot popper). The only modification was to replace the original catch spring with a slightly lighter one. The electric release is operated through a visible but disguised switch and a second hidden switch.
I've had this fitted for a couple of years without issue.
