Talk to your dealer to find out if your wires, clutch cable and brake lines need to be longer. Depending on which stock bars you have and how big the apes are you might not have to replace them, then again you might. I did replace mine. I have seen charts of this info. In any event you will have to splice the wires to feed them through the bars. The connectors just won't get through.
I have done this on two bikes, both with wires moved inside the bars. The first time I drilled the holes in the bars and was very careful to smooth out any sharp edges. Plus, double insulated the wires where they pass through any holes. Good ole shrink tubing. The second bike, my Road King, got chubby apes (1 1/4") pre-drilled. SOOOO much easier to fish the wires plus no drilling. Overall it is a little dificult. You must have moderate to good mechanical skill, the proper tools and a good place to work. Be very careful. Pinched or scuffed wires can be a disaster. One more thing, if you have HD factory alarm / remote find out what wire is used for the remote antenna. I didn't even think about this and later found out that it was one of the turn signal return wires which it now inside my handle bars. This greatly reduced the range of my key fob remote. A minor annoyance that could have been avoided.

Don't be sorry, THAT'S FUNNY!
