Rob, I've been looking at the documentation which tells me to connect the SV-EMS module to the SV network. But there's nothing I can find that tells me what connector to use on the back of the AF-5500. Is it the EFIS Expansion connector? If so then that connector is already being used for the avionics I have installed (Avidyne IFD-440 and L-3 NGT-9000).

Do I need to return the Dynon engine sensors and replace them with Advanced engine sensors?

Thanks.
