New EMS and primary instruments on a CAR3 aircraft

I have a certified 1946 Stinson 108. I would like to install FlightView with the new V3 and EMS. Bc it’s certified, I can installed (after you get approval) via NORSEE.

I need to install certified primary engine instruments but I would like to also use the EMS in FlightView.

Can engine probs be used in parallel between the Primary electronics international instruments and the EMS?
