This page may be of use if you install the Grand Rapids Technologies (GRT) dual EFIS package with a Garmin GNS430, SL30, and GTX330, and with a Digiflight II VSGV. This selection of avionics is not accidental; I picked them because they conforms with the two wiring diagrams provided by GRT (with Digiflight, with SL30)
