You would be able to tell us whether it's positive or negative ground better than we could tell you.
Find the batteries. Find a large wire going from one battery to the frame of the truck, or to the engine block. Does it come from a + or a - post on a battery?

Do you have a multimeter? It is a tool that you should own and be familiar with. It will be a tool that will be indispensible as you do electrical repairs. They are cheap, probably under $20 at Radio Shack.
