Hi all, new here so please bear with me! I just got a rear view mirror that has a rear/back up camera and forward camera that displays on the mirror. It constantly records even when the truck is off. I installed everything and thought for sure it was going to be easier than this! The wiring harness has a ground and two fuse adapters (batt & ACC). I obviously connected the ground and found the batt or constant power in the cigarette lighter fuse… but I can not for the life of me, find an acc fuse near the door to put this acc fuse adapter in!!! I’ve tested every fuse with the multimeter and can’t find anything. I’m beyond confused. Anyone know where I can find an acc fuse close by OR an acc line I can splice into? The leads are fairly short so distance to the fuse box under the hood is a factor. Thanks in advance.

 

Maybe a local car stereo shop could readily identify such for you.
