i got my viper 791xv installed in december, and ever since:

my third brake light doest turn on,

my trunk lights dont turn on when i brake, they only turn on when i turn my headlights on (but dont get brighter when i brake)

so basically in the day time when i brake all u see is my two outer tails turn on. as oppose to all five.

is this a fuse problem or.......?
