Plug the stepper motor wires in the correct locations on the RAMBo board. Ensure that you get the correct X Y Z locations.

In the image, X = Red Y = Blue Z = Magenta.

Secure the stepper motor wires to the top base plate with a zip tie in the location indicated.

Finally, you can plug the RAMBo's 40mm cooling fan in at the connector marked by the red circle.

This completes the top assembly preparation. Next, we will focus on the final assembly of the build.
