Truck won't shut off after after turning key off.

What is your question?

Every once in awhile i will turn the key off and the truck stays running like i never turn it off. Then it starts going haywire and I start hearing clicking and smell like burning wires.

What makes this problem better or worse?

It doesn't seem to change

How long has your 2002 Dodge Ram 1500 had this problem?
