I would think you would want to keep the VPX and IBBS as two separate independent systems incase the VPX fails? Power1 inputs for the VPX and power 2 inputs for the IBBS. What is the advantage to integrating the two systems?
The charge circuit for the IBBS is going to run through the VP-X, however the IBBS master switch will be independent. Avionics backup power with be via the Power 2 inputs on the EFIS(s), ADAHRS and engine module.
The shop that pre-wired my 6ah Li-Fe-PO IBBS for a G3X obviously got it confused with the 4ah NiMH and wired it incorrectly. No harm done as I was confused as soon as I saw Figure 20-1.3 filled in rather than 20-1.4. So I had to re-pin. No big deal.
Seems like there is a bit of confusion between the two floating around.
The Garmin and TCW install manuals are correct and consistent - as long as you correcty identify the hardware you are using
