Where are you tying in for auxiliary stuff like lights, radios, and the like on something as new as a 2012? I see what appear to be two fused "auxiliary lugs" off the power distribution panel under the hood? I'm trying to avoid cutting into any factory wiring... What about an source for "ignition on" signal that I can run a relay with? If I can get hold of an "ignition on" signal, I can pull from the battery and trigger things through a relay using the signal source. Thoughts?
