I just threw a set of Wild One 518's on my Fatboy(2002). You WILL have to add some wiring (which means soldering and shrink wrap). Running the wires through the bars was real easy....I just taped them together(after removing the "sleeve") and they went through like nothin,just had to grab them with a pair of needlenose when they reached the opening.Also, had to dremel the wire slot at the controls a little bigger,so the signal light wire could run inside the bars without being pinched. Nice bars,they improve the "comfort factor" a lot.
