Amazon Smart Thermostat install - C wire adapter help

Hello,

I'm attempting to install the Amazon Smart Thermostat but I'm having trouble when it comes to connecting the C-adapter to the HVAC unit. I'm attaching some pictures of the board as well as the wiring schematic. I don't see a C terminal to connect to! Can someone help?

Edit: Let me know if better pictures are needed.

Welcome to the forums.

Plenty of pictures.

It appears you have a Trane system.
With Trane.... B = C
In the second picture.... the blue wire on B is a C connection.

Hey Pjmax,

Haha better safe than sorry 😂. So at the end of the c-connector I would connect my C wire together with my blue B as shown in picture 2?
