For some reason it does not come with directions on how to hook up the wiring harness so i have no clue what to do. theres some stuff that plugs into the plugs already there but there are extra plugs that dont seem to fit anywhere. I know some how you have to connect directly to the battery or alternator.

You basically run 12v from the battery to the relay, and then to the pump. The stock fuel pump harness is used to just switch the relay on. It's very simple, but I've never seen the harness they do so I can't get specific. But the whole way in which it works is super simple.
