Seriously, I have no idea what " a bunch of wires" means.
Is it a Component output from the DVD player? Five wires?
Does the one you want to use have 3 wires? One?
There are adapters (some expensive) for just about any system match up. Just need to know where to point ya.
The manual for the DVD player you want to use is http://www.docs.sony.com/release/DAVS300_OM.pdf
It shows an S Video output (DVD only) and composite 3 wires output. It is a Stereo Surround Sound unit and hooks directly up to speakers. Does you camper have a Concertone unit in it now? If so, I doubt this will work without taking out just about everything.
