There are times when we might get lucky ---or not!
Winnebago has a form of "coding " that they stamp on the side of wires and then we can use a list to "decode" those letters.
Decoder list here:

Example of what to look for on wires in the picture below.
I went to the list, hit CTRL and "F" at the same time to do a search/ find which brings a dropdown where I put in "tank". That brought me a section to scroll through all the places in the list where tank appears. doing that brought me 43 spots to check and it gives the "from" and "to" of each wire with the specific label.
"AB" gets you a 16 gauge white wire for the ground on fresh tank sensor?
Maybe with luck you hit the right combo? But there does look like 43 choices!!
