I have my front USB ports working now. $5 extension from amazon and they are good to go. The rear also powered up as well so I am all set. I have not tried the smaller USBs above the regular ones as I have no plug to test them with, but the regular USB ports are functional now. Link to usb extensions below:

I have been doing the same swap and have gotten everything working, except the apple carplay no longere works. The usb plug has power and charges the phone, but will not connect to carplay. Did you have any issues with that? a solution?
