Trying to locate a switched fuse on 2013 Audi A5 convertible to install battery pack for a dash cam. I am using a add a fuse and I tried all fuses that would be considered a switched fuse like heated seats. Nothing is working. When the car is turned off the Thinkware battery is supposed to cut power from the car battery and use it's own energy to power the dash cam in parking mode. The car camera is plugged into the Thinkware battery pack. Any help is appreciated.
