Hello folks. I am new to the forum and have recently been researching how to fix my 4x4 problem. I was quite successful in finding a quick fix by switching the vaccum hoses, but I am wondering, does anyone have a picture of the location of the actual ADD relay? I think the placement is important on various models. I read though this discussion and I think I have experienced the same problem. Upon switching my vaccum hoses, however, my 4x4 indicator light worked again as I switched the vehicle in and out of 4x4.
