Ok, I would like to just throw a few things out there.
1- Have you thought about your AC vents when it comes to the Defrost?
What do you mean exactly?
2- I would try to incorporate your USB into the same Various switch section if possible.
You're probably right. I was just thinking of having it so both pass. and driver would get to it easily.
3- If possible I would add two (2) AC vents in the center of the dash (this can be for extra air for the driver and passenger or for the rear of the bronco for the rear seat or circulation).
As I understand from a previous post, BCB's A/C only allows for 3 vents. If that's wrong, then I'm all about 4 vents!
4- Where are you going to mount your fuze panel?
I'm actually going to have 2. Probably on the driver's side.
5-Add Tweeters in the place of your existing speakers and move the speakers just below the dash in a below the dash box (there are two options, with and without a hole).
I'm really picky about sound and just don't like only tweeters only pointed at my face. Just my preference.

I like that tunnel cover!
6- Look at post #164 (Rob did a great job with similar ideas to yours)
