A friend of mine gave us 2 electric sun shades for the front windshield. They have 2 wires and when hooked up one way, with the hot and ground, they go down, reverse the wires and they roll up.
My question is how do I use 1 switch for each side to roll up and down as they are designed. I know this is a stupid question but I am confused which way to correctly wire them to work.
Any help would be appreciated
