just got a "bury systems 8" handsfree kit for the car, ive been told theres a bit of loom tucked up behind the left hand side of the glove box, had a look but couldnt see anything, only thing i did manage to see was a small black box with wires going to it that said "VDO" i think there was a relay plugged into it (couldnt see it but felt heat from it?? the engine was of??) and i think i could feel abit at the other side of it for a relay to plug into, is this the bit im after or is it something totally different? if so does anyone know what this is?

cheers
