Fitting Rear Camera

[greencroft]

I'm in the process of fitting an Autovox W7pro reverse camera. Question is what is the best way to route camera cable. Due to Solid build and insulation there isn't a cavity to put power box and aerial.
Will I invalidate warranty if I drill a small hole behind number plate and thread cable down and out through rear light harness grommet?Any suggestions welcome

This will apply to other makes and I would post it in technical.
Not sure about the warranty, I would ask Eldiss to get the official answer.
