If I connect pin 7 from the AF-Pilot (Auxiliary Output) to one of the RS-232 inputs on the PFD EFIS and configure the port as AF-PILOT will I get status information as well as audible "engage" and "disengage" alerts, without connecting an RS-232 GPS output feed into pin 17 of the AP?

I know this is an odd request but my panel currently has a selector switch that allows me to directly select the GPS source for the AP...I really don't want to rewire it.
