I’m reengaging on this old topic in case it helps anyone searching for diagrams from Thor as I recently was.
When I contacted Thor a week or so ago, I wasn’t brushed off and told to contact my dealer/service center for the electrical schematic as happened before (2019 or 2020) but was referred to an "owners resource" page.
https://www.thormotorcoach.com/owners/ then go to Owners resource login (
https://www.thormotorcoach.com/owner-resource/)
I was amazed at the manuals, schematics, water line layouts, LP gas diagrams, etc that were available. I do t know how new that site is but I wanted to share in case it helps someone else.
