These aluminum tabs are the best I've found for routing wires.

I just use super glue from the hardware store to attach them to fiberglass

use these at the rocket company I work at in Mojave. I've been using them
on the e-racer airplane I've been working on as well. They can be purchased
in a bag of 100 from:
