Switching from a manual foot pump to electric

My 68 has a manual foot pump for my windshield washers and I would like to convert to electric. From past experiences if I remember correctly I would have to find a wiper switch that has the washer option built into it. The dash harness connector should accept the new switch but I can't remember if the connector is in the engine bay harness for the washer pump from the factory, does anyone have any info?
