Never mind....I think I have it figured out.
I am installing an AF5400 in my RV-9A. My airplane (I didn't build) has an AG6 annunciator with sensor inputs for things like flaps down, Fuel pump on for more than 3 minutes, etc). I'm not aware that it was attached to my AF4500s in any way, but I'm not sure. As I get ready to install this 5400 into the panel and "plug and play" it, how do I manage the AG6 with the EFIS, or is the AG6 a standalone item?
