Can anyone tell me if this is wired correctly? and if the 2 unconnected wires need connecting? http://s1108.photobucket.com/user/stoker1969/media/20130408_1252161.jpg.html?sort=3&o=0 the wire colours are not very clear but the 2 unconnected wires are yellow and black . I have replaced the airbag ecu as it was covered in coke or coffee but the dash lights are still on.
