Another option is to use a premade 'guitar' cable and replace one end
with the TRS plug, wired as you have noted. Saves some effort over
wiring the whole thing.

You can usually buy a set (usually 6 or 8) of T/S (or TRS) patch cables MUCH
cheaper than guitar cables, if you want to replace one connector.
Better still, they are often color coded which comes in handy when patching.
