Used a unibit and drilled a 5/16" hole in the R/H wing leading edge for the recognition light. Installed a MS35489-4 grommets. Made two standoffs out of .032 6061-T6 to hold the recognition lights and nav/strobe lights from the bottom skin. One is for the left wing. Drilled two #40 holes for #3 rivets for attaching the standoff to the bottom skin L angle. Attached with #3 AD rivets. Drilled a 1/2" hole through the front spar and rear spar for where those wires will go through. Installed 3 SA-655 snap bushings that are from Stein Air. These bushings have a 3/8" inside diameter. Laid out where the wire standoffs from Zenith will go on the rear spar, P/N 11-03987. Spaced them one foot apart from each other. For the nav/strobe wires I'm using 20 AWG 4 conductor shielded wire. The recognition lights I'm using 18 AWG 4 conductor shielded wire.
