I opened up the forward tooling holes on the top and bottom ribs. Then installed the conduit and RTV'd it in.
Also like Mike S said, install the tip fairing with 4-40 nutplates (available from Genuine Aircraft Hardware) and countersunk screws.
This is the top installation.
The arrow is pointing to the location of the opened up bottom hole, but pre conduit installation (sorry for the bad picture quality, i cropped this out of another picture)
And one more....notice the arrows are pointing to the opened holes.
Hope this helps.
