Determined location for Garmin GTP 59 OAT probe and drilled hole for it. Rerouted pitot lines using 1/4” snap bushings through the ribs. Also had to cut the cable ties on the wire bundles inboard from the OAT probe location to add that wire to the bundle. Re secured and remembered to add the serrated edging around the opening in the bay rib. Also clecoed the inspection cover tab rings inside of the lower wing skin (left wing)
