It appears that I can't get out of the Daytime Running light mode when it's dark. At night only my headlights are on. No lights on gauges or parking or rear running, radio, shifter or plate lights. All lights that should turn on with my full headlight system. I've check all fuses and relay. Any ideas? Could it be the sensor? Anyone have a wiring diagram for the DRL?

I think this is caused by an open circut to the dash sensor.
