Same here. I just wonder about that, the connector which is feeded to the ISO plug for light detection is not just 0 or 12V. It's regulated, either via a variable resisor (old car) or PCM (new cars) since it's supposed to dim the illumination of the radios display when you dim the dashboard. Will the empeg take care of that ? Anyways, nothing happens to my empeg when turning the light on. J.
