The M7 fuse is for the rear power outlet, selectable hot all the time or hot only with accessory power.
If your JK did not come with the rear power outlet, there may not be a wire for it in connector C6 under the TIPM, even though there is a fuse in the slot.
Go to this thread to see how to make use of M7 as the factory would do it: https://www.jk-forum.com/forums/jk-e...source-189556/

Since you are already running your RCA to that location it wouldn't take much extra work to get the power from there to.

I am really happy with the camera/monitor set up, I have a fully time camera mounted on my tire carrier and used the second video input for a camera mounted in my bumper that comes on only in reverse. It gives me a great view for backing up to a trailer.
