    alright guys getting down to the last things and I know this should be simple but there is a fuse block with 2 posts and a mega fuse in the middle on the passenger side right by the battery on the fan shroud. It has 3 wires that go to it( one long wire from the drivers side that runs the length of the shroud, another from the back of the alternator and another one from the battery. I'm assuming the long one will be on one post and then the alternator and battery wires would be together on the other Is that correct? I have a single battery setup

    Either or will be fine. If you have the long wire that goes to the main fuse box, if the fuse blows it will turn truck off where if it's on battery side it will run till battery dies
