5. Remove the clip holding the extruder cable to the printhead and gently disengage the plastic latches on each side of the cable holding the connector down.

6. Remove the old extruder cable and connect the new cable

Note: Take a picture of the path the original old cable takes inside the machine before removing to best replicate it with the new one

2. Place the bottom panel back onto the printer.

3. Secure it with screws.

4. Plug in and power on the printer to test the new mainboard.
