Boxer 2010 reversing light switch location

[Cottams]

We have a Peugeot boxer 2010 and can’t find location of the reversing light switch. Any help appreciated.

On top of the gearbox?

Thank you. Done some googling and it seems we need to remove the air filter and other stuff to get access to it so the job has been put on hold for a day or so .
