OK, look at the 5 pin connector for the 69232. There is a small mark shaped like this: > and represents pin 1.
Pins 1 and 5 are track power frm the 2-4-0 loco to the tender and go to the rear tender conmnector via a polyfuse for lighting passenger cars or for a sound car.
Here is how I wired the 5 pin tender to a 2 pin engine with the tender bulb changed to 24 volts and on all the time.

The tender bulb can be directional with a diode added in series to the bulb wiring inside the tender, or in the cable on pin 3 thus allowing the tender to be used with any engine.
And here is Stan's document:

This info was to show how the 5 pin connector is wired/used. Different engines will use different cable cross wiring.
I figured out the 2 wire adapter for my small 2 axle steam engines with only a 2 pin connector for track power.
The mogul has 3 wires for non-sound versoins, and 6 wires with sound. 2 for track power and another for either sound or light control, i am not sure which. 3 for chuff control.
I never figured out the mogul connection as I have moguls with original LGB sound units.
Also, I added a single axle power pickup to my 69232 tender and the 2-4-0 runs much smoother on my analog track powered layout.

Cable wiring can be dependent on which mogul gets wired as there were many versions. MTS vs non MTS, 3 wire vs 4 wire motor block power pickups, and the chuff wth magnets vs hall effect solid state devices.
MTS units had all the sound in the engine, speaker in the tender. Other moguls had all the sound board and speaker in the tender.
So giving out a generic cable conversion will not work for some, and could cause problems/damage a sound board
I do not have a 2019S, therefore I can not figure out more specific info on how to wire your configuration.
