hello the last two wires on the right read “t” on both but are different colors. I didn’t see that as an option in the nest compatibility. Anyone know how to proceed?

Those are most likely for an outdoor temperature sensor that the Nest does use and can just be taped off

The post above by Patrick is correct usually Trane uses this terminal with there equipment but it is not necessary to operate the system with other thermostats such as nest gen 3 leaning tstat

Hi folks,
@Jarper79, the T terminal is not needed for Nest Thermostat. As I checked for your current thermostat labels, yours is compatible with any of our Nest Thermostat. The wiring of your thermostat wires to Nest should go as:

Hello Jarper79,
Thanks for the follow-up. What type of Nest Thermostat did you install? Also, can you help us with your Nest Thermostat's power reading? If you have the Nest Learning Thermostat or the Nest Thermostat E, go to Settings, then look for Technical Info, then select Power. If you have the Nest Thermostat 2020, go to Settings, scroll down to Equipment, then tap Power Info.
Regards,
Zoe
