Locate the 4 pin connector that was included in the kit.

In the top of the machine take the 4 wires from the new extruder motor and insert the wires into the connector.

The connectors have a small tab that sticks up from them. This tab should be inserted fully until it latches into the window of the 4 pin connector. It is very important that this tab is fully seated into the plug!

Insert the wires in the order as shown in Figure 3. You can also see the tab on the wires fully seated in this photo.
