new truck
 

Hey, i just bought a 1995 B3000. And so far i love it..it runs perfectly and is midly good on gas. So far i put a magnaflow exhaust, tinted the windows, and put in a kenwood deck. The one thing that i was wondering about was in the gauge cluster. Its a small rectangular black box. Im not too sure what it is, or what its for, it looks like something digital....anyone?
