Recently my airbag light has come on the dash and as advised on here was asked to check connections under the seat. Well i have looked and found an unplugged connection and cant seem to find where it goes. If someone can look under their seat or better still can post up some wiring diagrams that would be much appreciated. By the way its a a single black connector with TWO brown wires. I have even taken out the seat ( its HEAVY !! ) and STILL i cant work out where this is supposed to be plugged.
