Researched diodes to use for Diode-Or power connections to the GTR200B and GNX375 (second connector).

Reviewed Digikey, Mouser and Stein Air carts, made some updates and placed orders.
The Mouser order included K1 and K2 panel switches, the key switch (master), relays for the small starter switch on the stick, diodes for the solenoids and relays and resistors.
The Digikey order included limit switches for flap position, a connector for the wires going to the pilot and copilot stick, diode-or dual diode packs, QC terminals (.187 and .110) and a isolated music input jack.
The Stein Air cart included a mounting bracket for the GMU 11, a defrost fan and grill, headset and mic jacks, the field circuit breaker, an LED strip light and a pitot static toggle valve for alternate static.

Continued update of schematic and spreadsheet.
