I hate these instruction sheets. I think they are drawn for people who can't read. It appears that in Step 16, that is the trailer HD signal light relay. A wire does run to the fuse box, but not to the battery. In step 27, the trailer wire "A" inserts into the empty slot of the gray connector in the fuse box, and in Step 28 that little piece is inserted to snap the wire "A" in place; to keep it from falling out. Also, it appears that there is another wire that you tie in place when you hook the other one to the fuse box. This should be for an electronic trailer brake controller. So, it appears that hooking it in to the fuse box will activate the anti sway electronics for the trailer.
I believe that once you have this installed, your Dealer will have to add the hitch to your build sheet and activate the lights. (if they don't work once you have them hooked up!)
