Wiring diagrams for MOST RVs are typically NOT EVER "released" to the general public.
If you must have it you MUST contact the manufacturer DIRECTLY and even then I highly doubt you will get them..
What is it you are trying to troubleshoot that you need the wiring diagrams?
Most RVs are dirt simple, you have a power distribution box which one half contains 120V stuff and the other half contains all the 12V stuff.. 120V side uses breakers and 12V side uses auto fuses..
Typically the power distribution box will have a 12V power supply tucked into the bottom of the box (AKA the "converter").. That takes 120V AC and outputs "12V" which supplies all of your lighting, furnace power and other 12V items along with recharging the battery..
