Use a thin pry tool or tweezers to carefully pry up and disconnect the two coaxial cable connectors from the logic board.

During reassembly, these can be tricky to reconnect. One at a time, hold each connector in place over its socket and press down with the flat of your spudger. The connector should snap into place.

The coaxial cable closest to the battery connector is responsible for the Wi-Fi Diversity Antenna. The other coaxial cable is for the secondary cell antenna. Make sure to reconnect them to the correct sockets.
