Just about an inch or so to the left side at the bottom end of the leds, I drilled a hole and hid the wire down thru the inside of sissy bar and ran under the seat and tied into the brake light. You have to drill a channel thur the sissy bar bolt gussets so you have room to slide the wire thru. Must be careful to drill slow and cool. With the bar off the bike and minus the pad, put tape over the oppsite side (end) of the sissy bar. Feed some string into your hole where your led starts. Hook your shop vac to the other end of the sissy bar and slowly feed the string as the vac sucks it thru the sissy bar. Its tough getting past the bolt gussets but as you see it can be done. Connect your string to your wire and slide it thru the pipe.
