When you operate the Chassis Disconnect Switch the vehicle has no power to start or run the RV Chassis.
So, I figured out that harness wire UUB, which comes from the Chassis Disconnect Lockout Relay in the Chassis Electrical Box to power the Chassis Disconnect Switch can be opened up with a single throw single pole toggle switch to provide a basic "ignition kill switch".
To kill the ignition, you first use the Chassis Disconnect Switch to disconnect chassis power, then you go to the chassis electrical box and flip the Chassis Power Switch Disable switch. To un-kill you flip the switch back and use the Chassis Disconnect Switch to connect chassis power.
The chassis disconnect wiring is protected by a in-line 5 amp fuse in the Chassis Electrical Box, so the switch needs to be rated for at least 5 amps. I inserted the kill switch in the wire in the chassis electrical box and mounted the switch in one of the un-used slideout circuit breaker knockouts.
