I’m using this page to collate all the parts needed to wire a Garmin G3X Touch system.
Unshielded: M22759/16 aka MIL-W-22759/16
Shielded: M27500-xxTG aka MIL-C-27500
|Single Conductor (22 AWG unless otherwise specified)||M22759/16 hookup wire|
M22759/34 airframe wire
|55A0111 Single Walled|
55A0811 Dual Walled
|Shielded Wire||M27500 containing M22759/16 or 34|

Ring Terminals (#8 Screw for Back Shell)
|18-22 AWG Single Wire||MS25036-149|
|14-16 AWG or Two 18-22 AWG Wires||MS25036-153|
|10-12 AWG or Three 18-22 AWG Wires||MS25036-156|
Note: It is preffered to have 2 wires per ring terminal and use -153 ring terminal (Page 25-4). However a maximum of 3 wires per ring terminal are allowed. A maximum of 2 ring terminals (6 wires) per screw fixing are allowed. If the backshell still does not have sufficient capacity use the daisy chain method for the drain wires (page 25-13).
