Recently purchased a Lionel Great Northern 3100 Steam loco that was in need of a new board. I ordered and received a replacement board but don't know where to solder the wires from board to tender. Would appreciate any guidance with this problem as I would like to get this beauty running...Thanks in advance.....Joe

I think you mean this FAR (Famous American Railroads) set engine 6-3100
If so, then this previous topic has diagrams

Thanks for the reference ...I will have a look....
Okay , I looked over the above reference on the board installation and best I can figure out all three wires coming off the board are group together and wired to male plug. That means only one plug goes from the tender to the engine. Not sure I got that right and it doesn't seem right to me. Any help would be appreciated...Thanks

The engine is a conventional train- it has a mechanical E-unit and pullmor motor. There are ZERO electronics in the engine. It can run completely standalone by itself without the tender even being attached.
This engine came with sound of steam- a static noise generator circuit in the tender that made a loud hissing static that poorly resembles a steam chuff on a good day. If it went bad- replacing it with the same thing is a huge mistake IMO rather than using a good modern sound upgrade- but it's your train and your money.
Again, in a nutshell- #1 the engine should run on it's own and had NOTHING to do with the board in the tender. #2 Since all the board in the tender does is make sounds- and badly at that- why would you expect more wires or connections? It's not controlling anything.
My further concern is the part that really matters- the engine running- this is from the time era where the lithium grease used when building these engines likely hardened in the worm gear area, and the first thing you should be doing is cleaning that out, adding fresh grease, lubing the motor bushings and then getting the engine running standalone without the tender.
Your engine is basically just a different paint job of this engine.
