Alright, GR8FLH you can either pay for the extention, or just cut the wire and add another piece of wire with couplings, or sauder them together and wrap them. Im not sure if there is extra wiring for the ABS, my bike did not have ABS.
As for the pulling wires through bars, i have never had a good experience with this. Its not fun, your gonna sweat, swear through a few tools.,....possibly... But it will eventually work out and be well worth it. I put my bars in a vise so im dont have to fight so much.
For the parts, actually nothing is powder coated. I use a Appliance epoxy paint on all my stuff. Its all in the prep. Chainsaw has a good sticky on this in one of the forums and I use a similar process. I had that paint on my street glide for over a year and almost 9 thousand miles with no chips. Good bang for your buck if you ask me. Ive also never had anyone question it. They are always like man the powder coated parts are awesome. You must have a bunch of money tied up in that I bet. If they only new I had 15 smacks and some elbow grease for an evening.
