Do you know if there's an adapter already there? Or does anyone know?
It's weird why it would be so hard to pry off
As opposed to others comments that transferring USB & Plug to the glove box being a "20 minute job" it was not for me. Maybe... if they had taken everything apart prior to this it would have been but if you have never been into the dash before count on taking your time and spending it patiently prying and trying, but be patient. I found plenty of YouTube vids on taking apart the center stack and that was important for moving the wires but in my '17 I still had to do some splicing on the cig lighter wires. The USB port DID have enough wiring to move around to the other hole, but I had to disconnect the holding clips at more than one place and reroute it after pulling the radio head unit out of the way. I was grateful for that as I did not want to splice that many wires into a homemade harness and hope that I did it correct given that there were data wires too.
Long story short, just transferring the components is NOT a quick and easy job.
There is no extra data port to plug into behind the square or round hole in the glove box like you asked.
If you want USB in the glove box, that has data to the head unit you will have to give up the center stack one and reroute it.
If you want USB in the glove box I would suggest picking up the parts in the attached picture below and punching a new hole into the side access panel that pops out (not the filter one in the rear) and placing the new hole.
Where you will find power to tap into... I'd say tap the present cig lighter wires... but that is only powered if you have the key on. I would not know where to begin to find full time hot on that side of the truck (but I am sure someone here does) other than the "right" way by sending a dedicated home run to your thermal fused hot fuse block next to the battery.
There is NO easy way to pop the round or square blanks BUT... if you take apart the lower half of your center stack first you will see exactly what you are up against by looking close at the round and square actual USB and cig lighter inserts... this will show you where to do your prying.
Hope this helps you out a bit...
Edit: I did not realize the retractable was in this photo... you won't need that. I got that because I also put this set up to the left of my steering column to power my phone hanging to the right of my A pillar in a nice and neat way. Don't forget to send some pictures when you get done!
