Strange Request Regarding Wipers

Hi I don’t know if any USA Mopar had a wiper relay fitted, here in Australia in 1976 we went to our wiper switch mounted on the indicator stalk, and has a 6 terminal double relay between the switch and the wiper motor my one has decided to fail, I have fitted 2 standard relays to keep the 2 speed wipers working but the park portion is not connected, so I was considering if there was an equivalent type of relay fitted to your Mopars that I could substitute
