TC30 wiring question

[Destr0]

So I bought a universal diesel ignition switch ($25 vs $180 for NH part). Question is where to connect the two glow plug wires?

NH wiring shows:
15/AC for accessory/ignition
30 for battery
17 for start
19 and 50 for preheat

New switch has
B battery -check
S start - check
I ignition - I think this goes to 15
F fuel (per diagram this is glow plug momentary on when key rolled back) 19 and or 50?
A accessory. ??

Anyone have any ideas?

19 when using the key roll back position. 50 is used to apply power to the glow plugs when the key is in the start position. Why? Maybe a pollution control thing

I had to replace the ignition switch in my Mitsubishi tractor. I used an automotive switch with no glow plug position. I did a work around by adding a heavy duty spring loaded toggle switch.
