Number plate fuse

[lukeboston]

I was just changing my number plate light and I must have blown the fuse because the lights don't work, either new or old and they did before.
Im just wanting to know which fuse is for the number plate light and where it is.
​Thanks

Ive found out it'll be a fuse in the TCU behind the passenger side lights - how do i get into the TCU?
