Servo wire braiding
I am using 1/4" wire braiding and 1/4" heat shrink. Notice that I have cut out my pieces measured with the lead on. Make sure to leave the wires on at least one servo to use to compare to keep the order of wires. I find it easier to note the signal wire for anything I have only one of such as the ESC rather than having to figure it out later. Red is always middle.

Remove the servo lead careful not to over extend the tab. In this picture I am using one side of tweezers with bent ends to slide under the tab while gently pulling on the wire. After removing the lead feed the wires through your piece of braiding along with your heat shrink. We will need to trim our servo leads if using Futaba servos with JR receiver see below. Otherwise reinstall the lead and heat shrink over the braiding and wires while still allowing it to slide on the wires.
