Using a pair of tweezers disconnect the vibrating motors connector near the bottom of the device.

Caution: these wires are very delicate!

Also note that while it may not look the same, this connector also lifts up, similar to the camera and battery connectors, and does not slide out.

Alternatively, you can also leave the connector plugged in and simply remove the vibration motor from the frame and keep it together with the motherboard as you remove it, being careful to not dangle it from the small wires.
