What the funk....?
 

Is there supposed to be a wire that goes from the positive battery terminal to the little junction box on the fender? And then two wires thatare part of the harness? One for battery gauge(black with inline fuses) and the other for starting truck (this one has the fusible link built into the wire)?

Is this grounding strap setup alright?

1) Box to frame
2) Cab to frame
3) Fire wall to block
4) Battery to passenger inner fender
5) Battery to alt. bracket
6) Driver Inner fender to frame

My passenger side low beam won't light up on low setting (it comes on when i turn on hi-beams ) and the yellow light on my grill stays on as soon as I plug the harness to battery.

I believe that is correct.
