hello!

even if pins are not marked- worth to measure voltage on all of them.
phone battery attached, phone powered On.
if you see on any pins voltage between 2,7 and 2,9 volts- this is Tx/Rx

hello!

take multimeter, set voltage measuring mode.
one probe set to some grounded part.
with another probe touch one by one all system connector pins or test points.
look for measured values. memorise pins with 2,7...2,9 volts.
they are Tx/Rx
remmember, phone must be with attached battery and powered On
