I ran both my antennae and my power and ground to my light bar up through the A pilar. The existing upfitter wiring was just slightly too small for my power and ground amperage draw to my light bar.... I would not use that upfitter wire for anything over a 15 amp draw and my KC light bar draws just over 16 amp and I wanted my antennae
mounted above the roof (as high as I could). When you are snaking up through the A pilar just be sure to tie back everything out of the way of the air bags.
