Hi, I recently bought an 07 Xterra and the cruise control works fine but every once and a while it kicks out or won't come. When it won't come on , the "set" just keeps flashing. Any idea what the problem might be? Bad wire connection or a relay gone bad? Also I would like to install a rear end with posi and the stronger rear end. Mine is a 3.13 ratio - not posi. Is there another vehicle that I could get it from, say a Pathfinder or Frontier that would bolt in and be the same ratio and posi. . Also, how would I integrate it into my vehicle wiring wise etc. Would I need some plug in to get it integrated into my computer in my 07 Xterra or could I just wire it separately . My Xterra is an "S" model.
Thanks for your consideration.
