i just picked up an esky ec-170 backup cam. Does anyone know of a good place to splice into an ignition wire to turn the camera on? I don't want to use the reverse lights because then the camera will only work in reverse. I want to be able to view the video while driving so I need a power wire that goes hot when the ignition is turn on. I'm looking for something in the rear of my 2006 XL Denali.
