While working on the electrical on my just acquired 328 I noticed a fuse holder without a fuse in it. It's located on the front of the ABS control with 3 others. Looking at the car from the front, it's the fuse holder on the left and has a white spot on it. I only see three fuses on the wiring diagram, 3 30,30. What does this fuse protect and what size should it be. Also where can I find a good last page of the ABS wiring, every one I download seems to have a bad last page.
