I asked both for the schematic and to see if we could find a solution to my problem.

Which is the trackpad connector? Is it J3103 in the shared pic?

Test it by placing the meter in diode mode. No power on the logic board. Connect the trackpad.

Red meter probe (yes red) to ground.
Black meter probe to point to test.

Test each pin on the trackpad connector. Post each diode mode measurement.

I checked each pin of J3103 and they all work
