So sorry for your loss. Welcome aboard the forum! I would check the Thor website for any and all manuals and you can call them or email them (using their owner's website) for digital diagrams of everything (wiring, electrical, plumbing, framing, etc.) for your unit. You will need the VIN of the Windsport so Thor can match the correct diagrams, and I think you need it just to use the owner's section of the Thor website anyway.
Hope that can get you started and there are lots of helpful and friendly people here who can help with any questions you may have.
