SV-EMS-220/221 Wire Harnesses
Engine and environmental sensors and transducers are connected to the SV-EMS-220/221 via
two connectors on the module: one D37M and D25F. Dynon Avionics offers premade wire
harnesses which break out the pins on these connectors and it is highly recommended that
installers use these wire harnesses. Table 28 below lists these wire harnesses and their
respective connections to the SV-EMS-220/221.
