I brought a wire down from the 12v power port for the TV. It runs down under the panel behind the seat, under the door step panel, then up behind the kick panel to the dash and over to a rocker selector switch I added in the blank spot next to the dash power port.
I believe the switch under the seat for connecting the batteries together just operates a relay to do the connection. If the relay power comes from the coach batteries it seems possible you could connect there. If you disconnect the chassis battery and there is still power at the switch then you should be able to use it. Don't know what amperage the circuit is fused for but it probably would be enough to power the radio if the radio doesn't have a high power amp.
