I found these taglines here: http://thefinancialbrand.com/taglines/
But I haven't found what you are looking for.
The current tagline I think is Together We'll go Far
There were many stations when Wells Fargo ran the stagecoaches so perhaps one of these had coined the phrase you are looking for.
It could even be someone back then that had left some words on a wallI remember a sentence from a toilet in Norway many years ago saying:
"Like mye hvor du ryster och slår,
den siste dråpen i buksen går"
(No matter how much you shake and dance,
the last drop will end in your pants")
