Man, I am so glad you found that item. It pained my to read all of the many ways you almost used to void your warrantee or jack your NEW RIDE up.
YES, THE OEM CONNECTION IS THE WAY TO GO! That's exactly what I did. I believe you may have more than one fuse box. If you do, check the cargo area. You can use the aux or stereo, which depending upon your fuse configuration, might be located there. It's easier access and you can quickly dismantle it before your take it in for servicing.
Regarding working within the fuse boxes, see my post about a certain tool you'll need to change the fuses, If your fuse box is anything like the renegade whose fuse box is located at the center of the 7th level of Dante's Inferno with an opening the size of a chihuahua's face to work within, after dismantling the side piece, (which is easy, but be gentle, it's plastic) and the bottom wheel cover which has 3 or 4 screws. Don't over tighten them. Purchase long surgical forceps, found on Amazon for like $6-$10+. It will allow you to access, pull and reinsert fuses with ease without trying to stuff your body inside that chihuahua face sized hole while attempting to reach that @$^○□¿☆₩$^& box. Cheerio.
