I went though this quickly, so maybe someone has already given this advice. I needed the pass through wires to connect my HAM radio to power in my 2018 SCREW. All of the instructions I found on this site and elsewhere said to remove the kick panel. I did that and watched videos where the fuse box was removed. I took a guess and found that if you release the glovebox and let is swing down, you can see the pass through wires if you look closely. Way easier to access than from the bottom with the kick panel removed. Watch this to learn how to remove the glovebox without breaking anything (this guy talks way too much, so skip to 3:40 to save time): https://www.youtube.com/watch?v=VDZ95zXqqvM Once you let the glove box drop, you can see the wires on the right hand side (at least I could).
