Volvo 850 question, is the 12v constant in the boot area?

hi

want to fit a towbar, but need the extra socket for caravan
fridge,ect, just wondered if there was a 12v in the boot area that
would supply it, not sure of amperage. or does it have to come from
battery?

Ideally, straight from the battery. Don't think there's a constant live of
high enough amperage in the boot. (only courtesy light and electric aerial)
I may be telling you what you already know but for those who don't, dont
forget to take the feed from the lights upstreat of the bulb failure warning
relay. regards, - Roy
