Top case flex cable for 1GHz, 1.25GHz, 1.33GHz and 1.5GHz BlueTooth 1 (A1095) versions of the 15" Aluminium PowerBook G4. This cable connects between the back of the trackpad on the top case and the logic board. It incorporates the trackpad button microswitch and sockets for the backlight and power switch. On the 1GHz and 1.33GHz non-backlit models of PowerBook, the flex cable is the same but the backlight socket is left empty.
