recommended. Stepper motor wire colors shown are for the StepperOnline motors. Check that the one you use matches for
the connection needed.

Put a
¾
” long piece of shrink file onto each one of the stepper motor
wires before connecting it to the cable 5 wires.
Connect the cable wires to the stepper motor
wires using a lineman’s splice (AKA, the Western
Union splice, and shown to the right), and then
solder the two together.
Heat the shrink file tubing around each of the
joints to insulate it from the other things it could
touch.
