1976 Dodge Jamboree

I recently bought a 1976 Dodge Jamboree motorhome. On the passenger side there's an opening with a bunch of loose wires, what does the wires need to be hooked up to? This is my first time owning a motorhome so I don't want to mess it up. Can anyone help me? Maybe someone who has the same motorhome can show me a picture of what I need to hook it up to.
