Clearance lights on rear of TM

I am considering mounting a rear vision camera on the rear of my TM2720. I had one on my previous camper, an Aliner Expedition, and found it to be a valuable tool. I can see into parking spaces without constantly getting out of TV and run back, I can also see what is behind me while travelling.

I have decided that I would like to mount the camera at the same level as the clearance lights, however, I don't want to risk drilling into the wiring for the lights.

Can anyone advise me what I will find in that clearance light area, is there a way to loosen an interior panel to route the wires for the camera and hide them from view inside?

Thanks in advance for your responses.
