So i spent yesterday afternoon after work sticking in the usb sockets i bought last week, I'm not saying it's the tidiest install ever but i didn't feel comfortable chopping up the plastics. This way its removable.
Chopped and drilled some wood, don't have the correct tools so just drilled lots of holes for the sockets.

"face plate"

Got the carpet out from making the drawers and wrapped it, bit fiddly with the small bits and i didn't have the stapler this time.

you can see where i missed while squirting the glue, can't see it from the drivers side but a little messy from the passenger side.

test fitting.

The new reverse lights came in handy.
@StarCruiser figured out what those wires were for on the passenger side battery. There were extra ciggy sockets. One was in the nsr cubby hole and the other tucked behind the centre console. I reused the earth from that one.

I discovered i'm really crap at soldering, really really crap but it's all together and working. Wired it into that power supply thing next to the drivers side battery so that its only got power when the ignition is on.
Q. How are you supposed to actually connect stuff to that? i took the top off and connected it, but with the wire there its not exactly flush when closing, and are those contacts already fused? If not i need to stick one in line.
