Center console was hacked like the 2001 Boxster S I did. Usb hubs are inside the center console.

I used a car kit so I could I tap into the system wires. Then I started to have problems. The car kit (wire kit) was wired wrong. I couldn’t find the true accessory and constant power. I end up taking the car of to one of my local car shops. After three visits the problem was solved. It turned out that the car didn’t have a true accessory pin so it was wired into the ignition.
