Hard wire wiper motor

[Grandpa 1]

Need some help trying to wire up a Honda Accord wiper motor without using the column switch.

I see a lot about how to wire using the stock wiring but not much on making it work with an separate switch. It’s for my 75 280z. Most of the links I click on cannot be opened or are expired.

I’d like to use a 3 way aftermarket switch.

Any help will be appreciated.

Thanks
