Thanks Johnathan.  I wish I would have color coded the wires between the Tender and Locomotive before I removed it.  I'm stuck between a rock and a hard place.  Tried several different arrangements with the wires with no luck.  Plus the plugs don't fit properly.  Bachmann should be offering an exact replacement. (They did but now it's Out of Production).  Makes me so mad that they can't help.

So my original wiring 4 pin plug that connects the tender to the locomotive went bad and I ordered a replacement. Unfortunately they don't have the exact replacement and said the other one would work.  Well No go and there are NO DIAGRAMS on which wires go to where. Nor was Bachmann very helpful.  Anyone have any suggestions or perhaps a wiring drawing?  Also the plugs don't fit properly.  Anyone else having these issues?

Can someone provide pictures of which wires go to which part of the circuit board (4-Pin plug between tender and locomotive.  Wires are ALL black with no guide !
