ENail Wiring Question

Hey all,

I'm making enails with my brother who makes custom wood worked boxes with exotic wood as well as pelican cases, action figures, all sorts of fun stuff!

So, I've wired them before going by my enail that I bought. I want to actually plan this out and learn about the wiring instead of just copying.

I drew out my plan.... Anybody here good with electronic wiring could help me out n let me know if this looks good? Thanks to all in advance!!

Not sure whose controller you're using, but it looks like you are using 8 and 9 for the thermocouple, instead of 7 and 8?
