The only way I would suggest to know what you are hooking up is to contact Jayco with your model and serial number. Ask them for a schematic of the audio/visual system. This way you will know exactly what you have to hook up.
I contacted them last year and they emailed me the schematic in less than 10 minutes.
Otherwise you are just guessing which cable goes where.
