Just found this great link for a parts catalog for Allison 1000/2000/2400 & gen 4 wiring parts.
company is located in Canada.

Too large to upload so here is the link.

This company is located in North Carolina.

And for those courageous enough to rebuild their own tranny, here is a components catalog.
This doc clearly shows the order or sequence of all the internal tranny components.

Here is a doc I found that really explains / shows in simple terms the wiring diagram-relationship, required for an Allison ECM.

Yes, the tcm got damaged we think by trying to start it with dead batteries, or when we hooked up the battery charger.
The tcm fuse for this bus was not located in the battery box it was actually hidden between the bus frame and underside of the bus floor right below the brake pedal.

We had no idea it was there!
When we found it, fuse was blown.
Got another TCM but they sent us the wrong one, one for a 1000 tranny not a 2000.

Fixed the old TCM, new fuse, bus shifts great now!!!
