On my 88 GW with all the smog "stuff".
There is some sort of belt driven devise under the steering pump, off set to the drivers side a bit? What is that thing? And what the heck does it do. The only thing that I can see that is attached to it is a low pressure air line, or heater hose? does it have to do with the smog stuff?

That's your air pump for pumping fresh air to your cat convertor.

It also pumps air into the exhaust manifolds.
