connector (the shorter cable) first. Then connect the speaker cable connector. Do not

underneath the lower center of the keyboard well. When the top case is removed, the 
trackpad cable is automatically disconnected from the logic board. However, when 
installing the top case, make sure the trackpad cable is installed securely on the logic 
board connector pins under the case. Use the connector pull tab and a black stick or 
needlenose pliers to carefully position the trackpad cable onto the pins.
Warning: When reassembling the computer, be careful not to pinch any cables 
as you press the top case back onto the computer. Check that the top case
