Hi Pete,
The Voyager Camera Adaptor # 31300006 would allow you to connect a Voyager RV Side Camera # VCMS12LGPR to a system with RCA ports. The yellow connector is for composite video and the white is for audio. Since you don't currently have audio you can just leave the white connector unplugged. The two power wires can be spliced into a nearby 12v power source and the 4-pin connector would connect to the camera. We offer the passenger side camera with a white cover with part # VCMS50RWT.... view full answer...
