Everything fine. The button fited my 2008 Hilux dashboard, its not very strict but doesn't come off easy either. The wiring description was perfect. I used a diode (something cheap that could come with this button if the seller wanted to show off). When I push the button my reverse lights don't turn on. It's very simple setup. All you need to do is use the diode between the positive signal from the reverse light and the wire that goes to do the camera, and connect the positive that goes back to the screen after the diode.
