Diesel equipment? Can I toss it?

[navybear70]

OK Chevy geniuses ... I have this black box w/ computer board inside hanging by about eight to ten wires under my dash. The box is open at one end. (see pic #1.) The wires go out the firewall and most of them end nowhere. (They are either disconnected, cut or go to picture #2.) One goes to starter? and one goes to distributer. Half of the cut wires are hot in the ON position. Is it from the old diesel system? Can I remove it along with the wires?
What are those two vacuum looking things in pic. #2? Ya like my wiring mess? This truck is a fire hazard...still. I have already fixed a lot of the splices and open ended wires under the dash too. My interior light was powered by open-spliced telephone wire.
