...on top of the ABS control unit. The control unit is a metal box, mounted horizontally just to the left of the steering column. Remove the two mounting screws. You don`t need to unplug the wiring harness, but it`s a good idea to disconnect the battery ground cable first. The relay is a 1" cube mounted on top of the control unit. If you disassemble the relay, you will probably find that the fusible link (9A) is fried. I soldered in a link from a 7.5A auto fuse. John 88 ///M3 Cinnabar
