I looked at your picture, if there is a fuse that says( tail), that should be it. You can pull the fuse and use the meter in series on the circuit terminals, voltage setting. With everything turned off, if that circuit went to ground, the meter would show system voltage. It shouldn't show that with everything turned off.
You could use chassic ground for your meter, the positive lead on the circuit leg, one at a time, see if anything is hot?
