Wiring bars
When I installed 10" mini-apes on my 06 FXDI, I was able to use the original wiring, but it was a stretch. If I had gone with 12" apes, I don't believe the stock wiring would have made the reach. I did not internally wire this set of bars. I'm not sure the wiring would have been enough, if I had.
I think you will find most who extended their harnesses went with a kit such as what is available from Novello:

These make for a much cleaner job, make wire identification easier in the future, and maintain the integrity of the wiring by reducing or eliminating soldered joints.
Another option would be to buy new switches. These come with plenty of wiring already attached at the switch. The also come with new terminals which you crimp on the other end once you have decided on the length you need. They are available from Harley, but can be found aftermarket for between $50.00 - $100.00.
Lastly, look at buying take-off Street Bob or Wide Glide switches. I later installed 10" mini-apes which were chrome and drilled. I did wire these internally. I used a set of take-off switches from a Street Bob which worked great. They required no soldering or crimping of terminals. Should be plenty of wiring on these, but verify it first.
Good luck,
John
