There is no ABS relay in my under-hood fuse box. There is only one terminal in the space for the ABS fuse. If all 94 one tons have ABS, how does it work? I've got a valve body below the master cylinder with about a four-pole electrical connector running to it, but what does it do? Mine doesn't pulsate when the rear wheels begin to skid, it just cuts the rear brakes out altogether. That gets kind of nerve-wracking in heavy traffic!!!
