The fuse for the brake lights and tail lights will be in that under-hood fuse box. The exact label might vary slightly depending on the year of your Saturn LS Wagon, but look for fuses labeled something like:
* TAIL: This is the most likely label for the taillights.
* STOP: This is the most likely label for the brake lights. Sometimes this might be combined with "TAIL" as "TAIL/STOP".
* RUN/STOP: This label covers both running lights and brake lights.
Important Note: Consult your owner's manual for the most accurate and up-to-date information on fuse locations and labels for your specific year and model Saturn LS Wagon. The diagram in the manual will clearly show the fuse box layout and what each fuse controls.
