This is probably on the fringe for what's allowed within before 1900 but hear me out.
It is known that in OTL the horse once inhabited the Americas before dying out in its homeland, surviving in Asia and only returning during the last 500 years.
I was thinking that the survival of North American fauna in South America is more plausible than as usually thought. As evidence I'll bring up the Camelids (Llamas, Dromedaries etc), the cougar, the spectacled bear, and the tapir.
Camelids originated in North America and gave rise to numerous lineages before dying out in their homeland at the start of the Holocene. They however, survived in the Old World and South America. The Llama group (Lamini) in particular once roamed the Rockies and Central America but now only remain in the Andes and the Southern Cone.
The cougar also provides an interesting case. They also originate in North America. In another thread (Tigers in Canada) I mentioned the extinction of cougars in North America at the end of the Pleistocene and how the pumas alive on the continent today are the descendents of South American pumas. The article is called "Genomic Ancestry of the American Puma" and it posits a return of pumas to North America during the Holocene from a refuge in northern & eastern South America.
The spectacled bear, now inhabiting South America, is actually the last of a lineage of bears that inhabited North America. Short faced bears were among the top predators of the Pleistocene Americas before dying off and leaving their last representative in the Andes.
Lastly, the tapir, originally inhabiting North America from Florida to Canada as well as China, disappeared from these regions and live today in Malaysia and South & Central America.
With these species in mind, I think one can make a case for the horse to continue living in South America, at least at the Andes and Venezuela. A study on the DNA of the Pleistocene South American horse Amerhippus shows that they could in fact be the same species of the domestic horse (The study is titled: Ancient DNA clarifies the evolutionary history of American Late Pleistocene equids).
The POD I have in mind is that a group of hunters in Venezuela either spare a herd of horses or comes to revere them as sacred. Since the global human population was quite low at the time period, the possibility of this group's beliefs spreading is decent. This small culture gives the horse some breathing room, allowing them spread southward into the Cerrado, Chaco, Pampas etc. during an arid phase 11,000-10,000 years ago. The culture vanishes eventually, but thanks to them the horse population recovers and becomes analogous to the bison in North America.
All that said, how do you think the survival of the horse in South America will impact the peoples inhabiting the continent? Does the horse become a small pack animal, allowing trade to stretch from the Andes to the Atlantic? Or are they ridden by nomads in the Cerrado, Patagonia?
(If I've exceeded what's allowed for Pre 1900, I apologize and approve of moving the thread to a place more appropriate.)
