extruder thermistor problem and changing pin

How can i change the default pin for the extruder thermistor? I'm on octopus pro, it's currently in T0, i want to move it to T1. I assume i need to modify something in printer.cfg. Using a rapido uhf if it makes a difference. I'm trying to troubleshoot a "heater not heating" error that seems to happen randomly. Sometimes it goes off as soon I start heating, sometimes after a couple hours. Otherwise the temperature seems fine. I believe it's due to wiring or a bad connection in the usual slot on the board (possibly damaged after i struggled to take out the connector) thanks for any help

I don't see T0 or T1. Did you mean HE1 (in which case the pin would be PA3 https://raw.githubusercontent.com/bigtreetech/BIGTREETECH-OCTOPUS-Pro/master/Hardware/BIGTREETECH%20Octopus%20Pro%20-%20PIN.pdf)

That's weird, the pin map i have is different. Is mine completely wrong? I guess i mean J45 in yours, now it's in J44. Thanks a lot!
