All stepper manufactures use different color wires. It is impossible to make a diagram for all of them. The diagrams do not even match the wires I sell. The ramps board axis plugs are labeled on the board, And I show it here, in the build instructions, https://www.vicious1.com/assembly/ramps-wiring/. Either z axis plug works they are the exact same.
I don’t understand the rest but I hope it helped, I can only do so much to help with hardware I didn’t supply.
