ANSWER: Hi Isaac,

QUESTION: light 1 is the map light switch inside and light 2 is the interior light switch.

Answer
Hi Isaac,
The map light is powered by fuse #3 in the main fuse panel. This same fuse powers the interior lights along with the ignition switch.
The brake light switch is powered by fuse #11 in the main fuse panel.
The power leaves the brake light switch to the brake light failure unit on to the brake lights. The brake failure unit is in the trunk near the ECU.
