This may sound silly question but I need to know how to wire this 4 terminal switch on a 12v vehicle. When you look at the back of it, the 2 terminals (thicker ones) are the switch but the other 2's got (-) & (+) marked on them (LED). I've got about 400Ω resistor to put in series with it, I assume (-) terminal goes to Ground and then do I connect the switched supply (+12v) to the terminal marked (+) via the resistor? Any light on the subject would be welcome, Max
