electrical smokepod ignition wiring

Hi,

I'm in the process of install the wiring to electrically ignite smokepods on the wingtips of my Pilatus B4.
I currently have small holes in the plates at my wingtip and wingroot, and a small metal wire is pulled through the most-front hole in the wing-ribbs. This
was all performed by a certified maintainer.
I can now choose what wires to run through the wings, what connectors to use etc etc.

Therefore I'm wondering what other (aerobatic) gliders have installed, and particularly:
- What kind of connector (chassis or normal) do you use at the wing-root?
- What kind of connector (chassis or normal) do you use at the wingtip?
- How do you prevent the installed wire from disappearing inside the wing, where you cannot reach it?

regards,

Roel
