I used to have a better color schedule chart but this page from Etrailer deals with trailer wiring schedule. When I repaired trailers I used a test light or meter on everything, never trusted that wire color was right. In a newer RV I might trust the wire color standard. One good thing about testing with a light or meter is that it may discover any other problems like low voltage or an open.
The link you posted is to E Trailer. The Schematic on that link causes MORE problems on the Internet. That link wiring is totally wrong and not to RV OEM wiring code.
