Got an external pump from alky control to replace my in-tank pump on my SMC Alky. The red and black wire seem pretty simple, hook to the black and red on new pump. I have two white wires on the pump that I thought he said were to control a selenoid. My two white wires come from in my tank and seem to be for the alky level. Do I just spice the white wires from the new pump into the ones running from the tank?
