I've looked at all the wiring diagrams in the service manual for my 04 Pilot, looking for a 12v line that's hot whenever the vehicle is running so I can tap into it for a rear-looking mini dashcam that I want to put facing out the rear window. I'm familiar with the wiring in the tailgate from earlier this year when I installed a backup camera and tapped into the backup lamp to use as the power and trigger for the backup cam. But what I need now is a wire that's always got 12v on it. I can't find anything in the wiring diagrams and I can't think of anything in the tailgate that's hot like that. Any ideas?
