wiring problem/??

hi all ..i have a 850 t5 (1996)saloon.after looking in the boot today .i found wiring block end with 3 conectors on it (1)red(2)blue/orange(3)black..this conector is on the right hand side as you look in the boot near the floor.being a saloon i guess these wires could be for the rear window wiper on an estate??cant think of anything else in that area what they could be used for ..the reason i want to know is ive just put a dog guard in the boot and i want to put a thermostaticallly controlled fan in the boot to keep the pooch cool,has anyone done this already or know anyone who has...ill be very greatful for any help....thanks terry:+ :)

Hi
On my 850 saloon I fitted the level sensor up gread for the alarm
it plugs in to a spare connector in the right hand side of the boot
in the well just in front of the lights.I think this is the conntor
that you are on about,but I cannot rember the colours off the top
of my head.
