Rx_A, Tx_A corresponds to CPU1,Rx_B and Tx_B to CPU2,phones Rx attach to box Tx(pin3),phones Tx attach to box Rx(pin2),Gnd to box pins 7,8.
But if You have good working cable (18A) -better use cable and do not demage the phone with soldering iron .I have tested 4 different hardware versions of this phone and each version has pinout directly in the connector. Gnd You can use even SIM cards metallic cover or TF card metallic cover.

try and test!
