Sorry to hear your troubles. Passing by here and seeing your messages...
You might email to Jayco directly. They have manuals and wiring diagrams for models back through 2017 available on their webite for direct download, but state they will furnish other years and models upon request. You might email or call them - they are very supportive and responsive. Perhaps, you've already tried that, but I wanted to suggest something since you are stranded and not getting many replies from others (surprising). Best of luck!
