Hot glue for me, whatever works for you, one hole drilled in that cubby(run the drill backwards or use a soldering iron. If you try to drill forward, you'll tear things up badly on this type of plastic), two little harnesses made to tap the existing 12v receptacle(you can just pigtail or splice).
I trimmed them to fit, but If you wanted to use a 2gang residential faceplate, it looked just fine, I did this instead. Those are TWO units side by side that fit in a standard switch plate. I should have taken a pic of them seperate. They fit so well they snapped in behind the lip that's already surrounds that cubby hole. Secured themselves without glue or screws(use gorilla glue if you want.)
I was originally going to go with six USB and one 12v,but changed to this configuration. One of the 4gang USB will go on the drivers side melted into the dash panel.
About an hour total.
The last pic is the tools I used. A butane soldering iron is a magical thing to own. It cut a really nice hole in that plastic.
Click the picture, then click the popped up picture and the picture will go full screen and zoom able.
