Here is the end result of the Click-Bond wire supports. You can see in the 3 photos (especially #3) that the actual part is quite small, compared to the contraption that sets them.
Photo 1 has the comm antenna held in place permanently with a quick tie. And photo 2 is holding the LED cockpit light wires. These were thin wires so the plastic quick tie wasn't secure enough on its own, so I used twine made for wire bundling to add more suport so the wires don't slide around.
In photo 3 you can see what one of these Click-Bond supports look like, with the green adhesive around the outside. Here the wires are held loosely in place with string just to hold them temporarily.
I also started splicing the headset wires. The comm radio harness wires for the headsets were way too short to reach behind the seats where I have my jacks, so I need to splice the shielded harness wires to the shielded wires I have coming from my jacks.
One to hold the comm antenna wire...
One to hold the LED cockpit light wires
And this is what one looks like, with temporary string holding things in place.
