I am installing a pioneer AppRadio for my 2004 S80 Volvo car, anybody know where to find reverse control signal from front fuse box or around of backup gear? i know i can find it in truck fuse box, but i don't want to run a wire from trunk, i am looking for closest connect point in front.
also for volv s80 car, where is ground connection in trunk fuse box? seems i cannot find it.
also i need to find constant 12 v supply in trunk fuse box, anybody know? many thanks.

I just see your post, I have installed the Appradio on my car, the reverse signal is connected correctly, the backup camera provides reverse wire, i don't have the issue with it. But i still have problem with dimmer sire connection, i cannot find the dimmer or lighting switch wire from S80, leave this wire open, then the screen has the same brightness.
