While working to mount my Streamlight flashlight in my recently acquired '99 Cruiser, I moved the seats around to facilitate easy access to my mount spot. Under the drivers seat I noticed a fan-type thingamabob and I am unsure of its usage and purpose. Looking at that spot from under the truck, there are two metal tubes leading to what seems to be the same object. Any idea of what it might be? Also, under the passenger seat there is a black box with a bunch of wires going to it. It's usage also I am uncertain of. What do you think it could be?
