I just got through putting apes on mine and had to lengthen the wiring. I left about 3inchs of the stock covering to push into the bar's hole when I was done. I had to cut all the wires and solder on a 8" section to each. I used red #18 wire and marked the ends that came through the base of the bars with black bands. ie. one band=black, two=white, three=yellow and so on. It ain't hard just write everything down.
Christian, American, Pro-gun, Conservative, any questions?
