Poking around in the coach today I discovered what appears to be a key switch of some sort mounted on the panel under the driver's window....below the park brake release button. I looked in the owners manual for the coach and there is no mention of this.

Can anyone advise the function of this switch?

Any chance it's an add on from a PO.

DW ejector seat arm switch?

Are you referring to the barrel switch? It has something to do with troubleshooting the transmission, not sure what as I have never had to use it.

I suspect that is the switch. Just curious about it since there was no mention of it in the manual.

When you go looking around in some of the equipment bays, you are going to find other switches that the manual doesn't talk about

I was told a long time ago that behind the panel is access to an electrical interface to the transmission. Never could find the key so I really don't know for sure. I believe the engine ECM and diagnostics are in the first compartment on the driver's side.

Its a diagnostics key, read about it in the chassis appendix section,
Engine diagnostic information appears as a blink code on the dash instrument panel.
The engine diagnostic key (Figure 7.3), located to the driver’s left, below the console,
controls whether the blink code appears.
