Hey,
I was installing a new head unit and accidentally let the +12V ground and well... I can't find the fuse for it!

I was doing this on a 2001 Caravelle. I have checked the fuses above the accelerator and in the engine bay near the battery but nothing appears burnt out.

It also makes the clock lose the time and the trip length clear every time the car is switched off.

If anyone knows the wiring and fuses for the constant power supply I would be very grateful.
