I do not know if this will help but pretty much all e2000 machines use the same wire colors all the Triax on the Iowa Board went to the same things it can be really difficult to find a schematic for an e 2000 by the time they did the wiring on those machines everything was standardized the greatest thing they did not like the old em machines where the wiring diagrams were scattered and all done by hand and no two parts are in the same place onto wiring diagrams they were horrible the newer machines were much better just about any schematic will help you dramatically
