Option A: Some motors can unclip from the wiring harness. Use the spudger to pry the white colored base of the motor from the gray piece on the end.

Clip the new motor into the gray plastic in the same configuration you removed the original motor.

Option B: If your replacement motor does not have wires pre-attached, snip the existing wires near the base of the motor.

Solder the snipped wires to the base of the new motor in the same configuration they were with the original motor.

Option C: If your new motor has wires pre-attached, splice the original wires with the respective wires from the original motor.
