Why are you moving the wires? Unplug the signals and leave the empty sockets hidden inside the controls, then splice into the wires inside the headlight bucket. That way if you want to you can still put the signals back in the standard position later.
The only reason I can think of to actually remove that wiring is if you're relocating signals AND hiding the cable inside the handlebars. Then it's a case of "why relocate cables you're not using?". And that's not a bad idea to do at the same time - that way you don't have ANY black sleeves to worry about.
