I'm trying to tap in to the purple wire coming from the rear hatch trunk release. This is the switch just above the license plate. I'm hoping to find the wire somewhere in the trunk, but no luck so far. Does anyone know if it's there and how to locate it? I'd prefer to tap into it in the trunk (or another place near always-on 12V) rather than have to run a separate wire from the hatch to the trunk. Any help would be appreciated.
