Joe,
Here's my advice on wiring:-
Keep it SIMPLE by keeping it NEAT!
Don't be tempted to use any old bits of left-over wire you happen to have hanging around. Colour-code all your wiring (if that means buying new stuff - do it! It will be a LOT easier to trouble-shoot later on when you've forgotten which wire went where).
And don't scrimp on wire by taking the shortest possible route - eg diagonal criss-crosses. Lay it out LOGICALLY - once again, it is far easier to trouble shoot later on.
Avoid hanging wires which can get snagged. Lots of such wires lead to "bird's nest" wiring!
Use terminal blocks liberally - they make it easier to isolate problems.
Here is a photo of the wiring under one of my NTRAK modules to illustrate the point.
The purple/white wire combinations all lead to switch machines. The green/black wire combinations are track feeders to the yard tracks.
