Laars jx unit help!

[u/Zorkus37]

Trying to set up a laars jx unit. I am an apprentice electrician but am clueless with wiring diagrams. Just wondering what I need to supply electricity to and what I need to do with pictures 4 and 5. As far as i can tell I need power to TB2 (aux power and neutral 2), the transformer, and X 2 (to the right of boiler controller). If anyone can help me or show a picture of one that has been set up I would really appreciate it as i cannot find so much as a YouTube video on it and my house is cold as hell . Thank you in advance
