Well, i am converting planes to MSFS (FSX ones), so far, so good, however, there is still a major issue:
While i use panels from the default planes (i copy them fully, no edit) and they DO work “correctly”, they do NOT show the Gxxxx instruments, they are just turned off.
The panel works properly and loads the proper textures, the switches and stuff work normally, and even the auxiliary “steam” gauges work, but none of the “modern” instruments work, they all appear turned off, and there is no way to turn them on.
I have this problem with pretty much all the default cockpits when i use them on other planes, i tried with custom AND default systems and cockpit cfg files, with no success.
I have installed the working title Gxxxx mods.
You’re going to need to figure out how to power them from the electrical system. Sorry I’d only be hacking at it myself, I can’t tell you how to do it correctly. You might ask @N95JPL , maker of the C152 mod
Unfortunately I can’t help with the GXXXX screens, I haven’t used any since the C152 is a rather simple beast 
and importing FSX aircraft is also very different from what I am doing
However, I do recommend making sure you have EVERY file double checked, make sure they are actually powered by the systems, check other mods that use the same systems, read through the custom Model Behaviour Files and ensure they match yours, it may be as simple as you’ve missed a “power connection” that is mentioned in the Model Behaviour but not your systems.cfg
I see i see, well, i will do that.
Well i checked, i can not find an error, i will post the electrical section of the Systems.cfg i made for my PC-12NG:

If somebody can check this out, that will be GREATLY appreciated.
It has more to do with connecting gauges to the electrical bus than it does with the screen I’m imagining.
I’m going to have to investigate this further, I’m not 100% sure! I’ll find some time soon, I’m guessing it’s something in the ModelBehaviours
Well first i just used the default TMB electrical system, but it did not worked.
Maybe i just need to set it to “electrical allways available”?, maybe there is some bug?, maybe some internal code blocks this on the sim?
First thing to check, did you attempt to turn the knobs on to turn them on. By default, they are usually off, especially with addons.
- The items need to be connected as listed in the panel.cfg and sometimes panel.xml matters.
If you aliased the TBM cockpit and used the TBM panel.cfg and panel.xml, and also used the TBM systems.cfg setup file, I imagine it should work. Just make sure you attempted to turn them on. As N95JPL mentioned, you’ve got to check ALLL the files. Did you use the TBM ModelBehaviors (that one is totally beyond me if it’s needed or not).
Dude… 
Yes, i did used the TBM files first, just with the PC-12 lights (panels and system cfg’s)
That is why i am so puzzled :S
Sorry, that answer confuses me. You used the TBM or PC-12 panel and system.cfgs with all of the TBM files for the cockpit?
It sounds like you know more than me. Good luck.
I am working on several planes at the same time, the ACES M20M, FSND C310Q, FSND R182RG and the ASOBO “PC-12” that comes with the simulator.
So far, everiting has worked properly, the planes load, display, sound and dinamics are fine, but not the panels…
Anyway, forget about the dude part, i was just too frustrated :S, sorry for that
