That here is my LTN72RH-Experimental kit: Once I will have access to the INS unit after Corona, I will use the documentation from the Laker Airways DC10s (bottom left), to wire up the INS to my 3 phase supply using a prepared transformer (left, top). The mode select and CDU panels (top row, middle) will be connected using cables prepared with the appropriate pins&sockets (top, right) and being plugged directly into the INS's rear ARINC404 plugs (numbered layout of these see bottom, right). Will be fun to see whether there still is life in my unit:
