Does anyone know what the Dummy switch is for by the dimmer switch? I looked through the side panels after reading this DIY http://newtiburon.com/forums/showthread.php?t=135929 and they said it was for the backlight. Idk what that is. Is it important? and can i hook up other stuff to it like lights and what not or do i need to get a TCS switch to do that? sorry if this is a noob question. give me a break.
