what else do i need? i think i need a solid top bracket and bushings? i have a 03 ultra classic electra glide
Already mentioned were throttle & idle cables, brake line & wiring extensions depending on the bars...Some will say not, but I agree on the solid top bar bracket (make sure the low profile one so it fits under your radio). You may need to change grips if you can't get your left one off without damage, so its a good time to think about that too...
Naturally, for the wiring aspects you'll need solder, flux, shrink tubing,some zip ties, etc.
Other than a lot of patience and beverages of your choice, I can't think of too much else. Let us know
I have the standard ergo bars in black and they are one of the best mods I have done to my bike. You do not need to change any of the wires or cables but you will not be able to see anything out of the fairing mounted mirrors.
