The other hole I cut was to give clearance to the air intake tube which runs from the engine forward to the air filter. There's not quite enough clearance as the tube disapears beneath the nose of the car so a small section has to be cut away firstly from the lip around the bonnet opening and then a section from the piece which holds the bonnet hinge fixings.
The cable you can see just pushes up out of the way.
Not a bad fit, of course it may need a bit more work once the body is on but should only require a little fettling.
This is the view from underneath showing how the GD air filter mounts inside the nose cose
