OK was current long before Ford cars...

I read somewhere that there is a Native American word "Okeh" signifiying agreement... but I like Och Aye as a theory...

however I also read somewhere that "moccasin" derives from the the Gaelic "mo casan" ( apologise for the spelling) - "my feet".

Pick the bones out of that...
