Working on a gray 785 Hudson.  The three wire connectors to the SOS/whistle were removed/lost and the new owner of the engine would like them replaced.

I have three wires coming out of the circuit board in the tender (brown, black, blue) and nothing from the back of the engine/brushplate.

I have a pair of spare connectors with wires attached.  I just need to know which gets soldered to where on the engine brushplate.

Thanks in advance,

John

Here’s a pic of a 785 from the back if that helps....one black wire goes to the grounding lug, ( engineers side, lower corner ) the other black wire goes to the jumper lug ( engineers side) the blue center wire goes to field hot ( center lug ) .....take a look how I left the plug facing with the pins oriented the way they are....hopefully, you can distinguish which way it faces.....
