Electrical Problem Please Help

Hello, this is my first post here at Dodge Talk, hopefully im posting this in the right forum, and hopefully someone could help me out.. My wife was driving our 2002 Dodge Ram Sport down the road the other day at night and then all of a sudden the interior lights went out, all of the gauges (heat, gas, battery, temperature) went out, the windshield wipers wont work, the power doors wont work, horn doesnt work, and the headlights wont go off unless the engine is shut off.. The power windows however, do work. The red security light on the dash stays on all the time. The radio and the radio lights also work.. the light under the hood works.. Power seats work.. the engine starts up fine.. just all of these things dont work.. All of the fuses are fine.. Any help whatsoever would be greatly appreciated, thanks in advance
