Have you checked all the bulbs, where applicable? For the tail lamps check fuse 9--20 amp. Not only check the fuse, check for voltage on the fuse circuit. Do the park lites in the front work ok? You may need to check the wiring circuits at the rear. Brown is voltage for tail lamps, black is ground wire. The voltage feed for that circuit comes from the headlamp switch.
