Body Computer

Can anyone tell me where the body computer for a 94 carvan is located and what it's duities are.

It is located just to the right of the steering column behind the plastic knee bolster panel. It controls things light headlights, interior lights, instrument cluster, door locks alarm, windshield wipers, overhead trip console, warning chimes, some of the keyless entry operations, communicates with abs computer and airbags system, etc.
