I've installed a Blunami 2200 on the Large Scale 4-6-0 PNP with Battery power.

In the app, set Lamp type to Incandescent.

Connect the Blunami wires to the corresponding J1 pins as follows:
J1-1&2 to black, 3 gray, 4 white, 5 not used* , 6 blue,  8 green (smoke), 9 yellow, 10 orange, 11&12 red.
ALSO connect (jumper) the black wire of Blunami to  J1-7.
This accomplishes what the 4-6-0 instructions mean by connecting the decoder negative output to J1-7.
I also connected J2-10 (firebox flicker) to the white wire (jumper to J1-6), so the firebox goes on with the front headlight;
presumably you could use a separate function for this if you wish.

For sound, connect the thin purple wires (from the other end of the decoder) to J2-1 and J2-3.
*The Blunani doesn't use the chuff trigger, but electronically senses the motor revs. In the app, you can sync the chuff rate to the motor speed with CV-114. I found the value 25 works for my loco, giving 4 chuffs per rev.
So far, I haven't used the other function outputs.

BTW, the Blunami 2200 (2 amp board) powers the 4-6-0 pulling 5 Bachmann "Big Hauler" cars on a level track, 8' dia. curves, with all lights on and sound at full volume. I'm using a 9.6v battery.

Re Lighting for Bachmann 4-6-0 PNP
It appears that the lamps are incandescent.

I've installed a Blunami 2200 on the Large Scale 4-6-0 PNP with Battery power, and I finally have the lights working.

In the app, set Lamp type to Incandescent.

Connect the Blunami Blue, white, and yellow wires to the corresponding J1 pins in as normal.

ALSO connect (jumper) the black wire of Blunami  (also connected to J1-1&2 as normal) to J1-7.

This accomplishes what the 4-6-0 instructions mean by connecting the decoder negative output to J1-7.

I also connected J2-10 (firebox flicker) to the white wire (jumper to J1-6), so the firebox goes on with the front headlight;
presumably you could use a separate function for this if you wish.

I posted the full details for installing the 2200 to this topic:

If I install the 44958, (or some other decoder or PWM motor driver) do I need to remove the circuit board attached to the motor, or to the polarity switch?  I'm guessing this is a capacitive circuit that might possibly short-circuit a DCC signal.

If I do disconnect the circuit board and wire power directly to the motor,
what are the consequences?

BTW, ACD134, how are photos and video coming along?

Just posted to this thread, but now the "next" button goes to the next thread,
not next page i the layout thread like it did before.

I don't see much use for Toby without Henrietta.  But just curious--would the real Toby-Henrietta run backwards for a return trip, or would there be a turnaround? I'd think Toby-Henrietta should run back and forth, nor round and round.
