Winnebago is about the only manufacturer that has wiring schematics, electrical equipment installation drawings, plumbing drawings, and complete parts lists, for everything, going way back, ONLINE. It is very nice and adds value to the WBO products. I made good use of them while I owned my '07 View, and they come in handy when helping others online who don't understand electrical schematics.
Some manufacturers will tell you its proprietary information they cannot release, meaning, they do not have it, or they don't keep such stuff filed for the future.
Artic Fox does use an outside vendor to build up complete wiring harnesses, with connectors, and bundled, ready to install, so they should have the drawings, they do not wire on the fly.
See this video, at 17:25 he shows you a harness and explains this.
