I was wondering behind the gauges which wires lead to or are involved with the tail lights? THe wiring diagram I have says its the brown one on the direction switch connector. I turn my headlights on and the tail lights do not come on. They were working before when you put the brakes on. All fuses are good to. Also would the panel dimmer switch be involved at all with the tail light wires? I think I need a new one.
