I provide a complete schematic of my RV-9A in editable format here:
Vx Aviation.
You'll need to download the free editing software as well (follow instructions on the site).
My panel is using a D10A, GTX-327, SL-40, GPSMAP 296, RMI Micromonitor and miscellaneous stuff.
I'll post my HR-II schematic in a few months, once it's finalized. It will similar, but updated with current EFIS and using a fully centralized electrical switching system using automotive relays.
Good Luck
Vern
