So my fuel gauge is not working, well works enough to tell me weather its on high empty or low empty. after getting under my jeep to check the wiring today i saw that my wiring is shot right where the fuel pump wiring goes threw the metal of my jeep by the back drivers side hatch area,(kinda hard to describe) anyway how do i get to the other side of the wiring to rewire it. all 3 wires are pretty bad chewed up
