I have a sqeeking noise coming from a Aluminum diecast box on the frame rail in front of the left front tire. It sounds like a squeeking accessory pulley, but is definately coming from this box (it looks like a small silver ignition box-and has an electrical plug and what looks like a speedometer cable going to it). Does anyone know what this is and how to fix it?????

could it be the thing that controls your intake runner flap? follow the cables and see where they lead.

thats the DSI controller, run a search for "DSI noise" you should find plenty of topics

^^^IMRC motor. (Intake Manifold Runner Control) is what's making the noise:

But...
Have you checked the DSI clip at the intake manifold?
If it broke, the IMRC will continually activate to try and pull the cable:
