I had the same problem finding the ABS plug, I removed the cover under the driver side fuse box, down in the foot-well, and eventually found the plug tucked up in the very right hand side, behind a plate. My leads were very long so the plug can go down a very long way amongst all those looms.
if you see my earlier ABS thread, i had to replace the relay before the light would go out correctly, after clearing the fault.
Hope this helps :?
