What are all of the wires above the rear birth for?

I removed the panel above the rear birth/bed to install a USB charging port and found a bunch of unused wires with connectors. There was a set of 14guage power wires which made installation of the USB port easy.
There even was a red 4 gauge battery wire tucked up there bare.

Question:
What are all of the wires above the rear birth for?
The boat hasn’t been modified.
Most equipment that I have seen is original.
It doesn’t have a generator.

Don’t know, can you post a picture? Most likely there for growth of accessories.

Part of it maybe factory but it looks like a previous owner chopped it up.
