The mogul has 3 wires for chuff (comes from engine rear axle sensor) and 3 wires for power (Tenders have track power pickups and are tied to the engine via the switch in the cab).

69232 has 2 wires for power to the tender. Other 3 are common, light, sound as these are controlled by a switch in the 2-4-0 engine. The 2 wires on the outside are the power wires to the rear of the tender.

I have done 2 wire conversions/non moguls.

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:
http://1stclass.mylargescale.com/danpierce/69232conversion.doc

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.

I have some 6 pin connectors and can make a 6 to 5 pin cable if you send me your 5 pin cable with the twisted wires, I do not have any 5 wire connectors left
I have never used the twisted cable with my 69232, only the straight 5 wire, orr the twisted one modified to a 2 wire connection with a diode for the tender light for analog track power.
I do need someone to verify the 3 wire mogul wiring, I know that 2 wires are track power and the third is for the rear tender light and is controlled by the switch and diode in the engine cab.
I could assume it is 3 of the more modern 6 wire mogul wiring, but I would like to be sure.

The 69232 does not have a chuff sensor input that I know of. It is voltage dependent.

If rewiring to a 2 wire connector likeI did, be sure to change the tender bulb to a 24 volt plug in version. And i added a diode to the center pin to make the tender light work in reverse only.

My 69232 tender appeared to have a 8 volt bulb. It was dim at 5 volts!!!

LGB sold 5 and 24 volt plug-in bulbs plus the 18 volt yellow bayonet base bulb.
These 5 and 24 volt bulbs were available in clear and red.
I obtained several packs of each last year for servicing my engines and the clubs engines. I am a spare parts nut and must have over 100 of these different bulbs.
Plus, I do convert to bright white leds and have used the Richmond controls golden leds.

A bright golden/yellow led would work well in this tender with a 1000 ohm resistor for track power operation.
