The radio had three inputs for my cameras (jensen 4pin type) the trigger wires are tied to the radio as well from the harness ie reverse and turn signals. I found a voyager csw3 switch that is perfect but no longer made
I couldn't find anything on a Jensen jr2212? I would think pictures or manuals would still be around for a 2015.
Regardless, are you saying the your unit has not no on/off switch or the switch on the unit stopped working?
Is it possible that your unit was rewired since factory?
Does the radio otherwise work like it is suppose too ( meaning radio functions and cameras)
From what I read, I wouldn't think your radio could drain your chassis battery. Physically not possible in most my coach. If power left on it would drain my house batteries at least until time that the AGS started the generator to prevent low voltage.
You have not said anything about age or condition or chassis battery? It is possible that radio may have been switched on my mistake but chassis battery is going bad anyway?
If it were me, I would ensure chassis battery is good and passes a load test. Then I would turn on my Radio and play music for at least an hour to verify no change in voltage. If it draws of chassis, I would check wiring so it draws from House. Regardless when you turn off the ignition and assuming manual switch for use on house batteries is NOT on, there should be no power to the radio ( any radio) to draw current.
