Tolusina has posted a diagram of how to create a home made power window controller. I have the photo of it.
Can I please get an english explanation of where each wire goes? I skipped electronics 101 in school.
Since whatever controller is made must switch both positive and negative at the same time to get the windows to go up and down, I just goes over my head how that diagram he posted does that.
I can see how a single lead gets turned on or off with the toggle switch..but both leads must be switched simultaneously as far as I know.
If you only apply positive to the left wire, to go up lets say, what grounds the right wire?
And if you apply positive to the right wire to go down, what grounds the left wire?
