I have a car radio hooked up in my room on my gaming chair and was trying to wire up a dimmer for the faceplate. It has a orange/white wire on the harness that say its for illumination control (dash dimmer switch). I tried using a potiometer or how ever it's spelled, an run 12v to the pot then the orange wire. I get varying volts out of the pot but the face plate only dims down a hair and stays there. Same if I just applied 12v to the orange wire. I've looked all over the Internet and can't find anything. Anyone have any ideas?
