Here is a simple way to hide the handlebar wires and clean up that area .
You will need the following parts & tools :
Drill with 3/8" bit , Phillips head driver
8 conductor phone wire , notepad and pen
Solder , Heat shrink wrap ,electrical tape
Round file , Butane lighter and soldering gun
You will start by removing the control units from the handle bars.
note: you can leave the grips and mirror mounts . Just remove the end caps from the grips .
Drill a hole into the bar on each side in a location that will be covered by the controls.
Angle this hole as much as possible toward the center of the bike.
Also drill a hole in the lower part of the bar (in the bend ) for the wires to enter the bar. Angle these holes toward the bars end.
Use the round file to get rid of burs in these holes after drilling .
