What wires under hood power the windshield washer pump?

[ClayJ]

I recently put one of the dual tanks under the hood, with radiator overflow and windshield washer w/ integrated pump. Now I need to power the washer pump, but I have no idea which wires long ago used to power the original pump.

Are the wires drivers side or passenger side? Up near the front or back by the firewall?

My bronco is a 1970

Looks like a green/black and brown that come right off the harness at the driver's side headlight. I can snap a pic if that helps.

Green-black wire from the wiper switch to side marker light area. Black wire for ground also ties into side marker and turn signal ground point.
