Had my sound system put in on my 2010 g37x and when I left they were working. But wither coincidentally or accidentally my rear lights dont work. Including the stop lamp. The tail lights flash when the hazards are on, the turn signals work and reverse lights work. So the powers there, I just dont know why this is. I changed all my fuses, although i cant locate the tail light relay. About to bring it to a dealer, gonna get hosed though.
