YUP! Got to agree that Winnebago drawings are totally different than others that I've looked at. Maybe some help would be to check on this page for some hints on what they mean to do:

But if you get into looked at them a lot, you are likely to find there are some real big things missing or left off. And some of those things they leave off make it really, really hard for new folks to figure what they are saying.
Example of things to watch out for when trying to read the drawings is that there are lots of mistakes and this part where you are looking has one. If you look for where the other plug is on the drawings, it shows at A3 but it is really found at more like A5, so you have to be alert and look around to find where they really mean?
And there are lots of things on the drawings that they leave off if it is where the coach/RV items may get power from the start/ chassis section. They consider what they add but often don't show the part that is installed by the chassis folks. Just leave it blank !
One big place wherer that often happens is on the mode solenoid that connects the two battery groups together at different times like when we want to get some charge into the coach battery as we drive. The mode solenoid has a connection that is hot when the engine is running and it pulls the solenoid to close a big contact between the start and coach batteries-----but they don't show the start nor the coach batteries on that part of the drawing for your RV. Sometimes they show the coach batteries real clear but leave off the start battery or just show a wire going to an "isolated stud". That isolated stud also has a battery cable from the start battery but they don't tell us that!
Then the wire code on the drawings can be hard to figure because it might be the wire color if it is something like "red, blk, etc." If you see 6 blk, don't try to look for the code as that is a number 6 black wire!
A 300 watt inverter is what they used to add but now if they do an inverter it may be bigger as they found out we want more power than 300 watt. Maybe it was to run a phone charger??
