Some background: I’m not an aircraft developer, rather, I’m an Integration
Engineer working on a sim conversion from X-Plane to 2020. I deal mostly with
micro-controllers and sending/receiving data using the above aforementioned
VAR architecture. But I am thoroughly confused about a few things (My first
conversion effort) so I’ll try to summarize: I’m working with the Black Square
KingAir350i mod. In particular, the AVIONICS switch. There is an LVAR called:
var_avionicsMasterSwitch
It’s a BOOL, so, setting it to 1 obviously ‘turns on’ the Avionics, but… it
doesn’t. All it does is animate the switch. It does nothing else. In the
AnalogKingAir.XML file is this snippet:
AvionicsPowerSwitch
(L:var_avionicsMasterSwitch, bool) 100 *
(L:var_avionicsMasterSwitch, bool) ! (>L:var_avionicsMasterSwitch, bool)
(L:var_avionicsMasterSwitch, bool) if{
(L:var_avionicsMasterBreaker, bool) if{
4 (>A:BUS LOOKUP INDEX, Number) (A:BUS CONNECTION ON:17, Bool) ! if{ 4 17 (>K:2:ELECTRICAL_BUS_TO_BUS_CONNECTION_TOGGLE) }
2 (>A:BUS LOOKUP INDEX, Number) (A:BUS CONNECTION ON:19, Bool) ! if{ 2 19 (>K:2:ELECTRICAL_BUS_TO_BUS_CONNECTION_TOGGLE) }
3 (>A:BUS LOOKUP INDEX, Number) (A:BUS CONNECTION ON:21, Bool) ! if{ 3 21 (>K:2:ELECTRICAL_BUS_TO_BUS_CONNECTION_TOGGLE) }
}
}
els{
4 (>A:BUS LOOKUP INDEX, Number) (A:BUS CONNECTION ON:17, Bool) if{ 4 17 (>K:2:ELECTRICAL_BUS_TO_BUS_CONNECTION_TOGGLE) }
2 (>A:BUS LOOKUP INDEX, Number) (A:BUS CONNECTION ON:19, Bool) if{ 2 19 (>K:2:ELECTRICAL_BUS_TO_BUS_CONNECTION_TOGGLE) }
3 (>A:BUS LOOKUP INDEX, Number) (A:BUS CONNECTION ON:21, Bool) if{ 3 21 (>K:2:ELECTRICAL_BUS_TO_BUS_CONNECTION_TOGGLE) }
}

Here is the Bus Architecture from the SYSTEMS.CFG file:

bus.20 = Connections:bus.21#Name:AVIONICS_BUS_3
bus.21 = Connections:bus.3#Name:INTERMEDIATE_AVIONICS_BUS_3
My question is in 2 parts: 1. How to I actually get this Avionics switch to
“Do” something, (Like turn on all the radios, etc…) What does that bus logic
do? 2. Do the WWISE events actually need to be called to perform this action?
If so, How would I call/reference those WWISE events? Any help is appreciated.
Like I said, I’m VERY new at this. (I learn by example and by watching others,
so if possible, please don’t tell me to read the docs. 
I’ve spent 2 weeks
pouring over mountains of docs and am no further along than I was when I
started, unfortunately. Thanks all. PS: This is the project:
