Normal way for me to do this kind of adapter is to install all resistors ( using insulating shrink tubing ) inside the connectors. There's plenty of space for 1/4 watt resistors and insulation. Use 3 resistors in the xlr's then the remaining two of each in the 1/4 inch . Again keep lengths to the bare minimum extra short :)
Adapt ad lib for different weather and terrains/situation. What's good in the desert ain't in the mountains or the cold conditions up in Canada. My first order of business anywhere in such a kit is an aluminum emergency blanket. I know the kit might get a bit bigger , but it's essential that one stays warm. If you want to be thorough have kits assembled for different activities. Never underestimate local weather in your decision making on contents of your survival kit. There is no " universal " kit that will be a help in ALL situations. Choose wisely.
