I know it's not a 4x4 but my 84 Mazda B2000. When you shut off the switch nothing happens. It just keeps on running. If you pull the coil wire it will die, but then all the dash warning lights come on. I tried replacing the switch but it still does it. I have resorted to pulling the fuse under the hood to shut it down. My thinking is there's a relay that's stuck, but I can't seem to find it. Does anyone on here have any ideas? My Bronco II just doesn't haul enough fishing gear so I need to get this truck running right. Thanks a million gang, John.
