Ok the group of 3 15a fuses in line are what you used. The first one. However my fuel pump relay is under it and I think the fog lamp relay is powering my trailer lights/tail lamp parks.
Also, concerning those 3 15a fuses, they all go to the parking lights. From left to right is trailer parking lights, left side parking lights, right side parking lights.
I tried all 3 when I installed mine and it doesn't matter which you use, just whichever is easiest and not blocking other fuses (although the add-a-circuit will still work if there's other fuses above/below where you install it, as it sits higher off the panel). It just makes it so you don't have to pull the add-a-fuse if you need to check/change the fuse it's blocking.
Turn on your parking lights then pull each fuse individually and watch each side light go out according to which fuse you pulled.
