Just getting on the forum. I have a 52 pickup that the PO installed a 12v EZ wiring harness. I am trying to get the 6v wipers to work with a step down that was already installed. The step down glows red hot when the ignition is turned on. It has 12v going in and going out. I bought a new step down and looked at the wiring diagram and it shows the switch first then the step down(s). I want to retain the original switch to the wiper motor, so how can I accomplish this wiring feat? Thanks so much, Greg
