Aftermarket washer fluid pump wiring?

[dodge68charger]

Hey Guys. Looking to install a washer fluid pump on my build. Car is far from stock and using an aftermarket painless universal wiring harness..

Just wondering how i go about wiring it. Theres only a positive and negative wire coming off it. Do i need a momentart switch as well?

Dash is custom so no stock switches

Thanks

Momentary switch or many wiper switches have the push button for the washer.
What wipers and switch are you using?
