Route the endstop, Y-steppers cables as shown in the picture.

Carefully insert them inside the drag chain and make sure the cables don't get pinched or twisted.

Route the cables to the location where you desire to have the electronics components.

Cut the cables to the final length, double check if the cable has the appropriate length before cutting.

Label the cable at the end, with a piece of duct tape for example.

If the endstop cable is too short, use the provided 3-wire cable and extend it following the same procedure as for the stepper motor in Step 14. Make sure to respect the colour order.

Repeat Step 14 and Step 15 for the second Y axis stepper motor.
