The iPhone 6 Plus uses a linear oscillating vibrator.
Pry the vibrator connector cable up from its socket on the logic board with the flat end of a spudger.
Use the tip of a spudger to disconnect the interconnect antenna cable from its socket on the logic board.
Grasp the interconnect antenna cable with a pair of tweezers and carefully de-route it from its channel on the vibrator assembly.
Remove the two 2.5 mm Phillips #00 screws securing the vibrator to the rear case.
Remove the vibrator from the iPhone.
