Installed the left wing OAT probe. This is the probe for the Dynon D10A EFIS, which will be my backup flight instrument. I located and drilled a 3/8' hole near the middle access panel using a Unibit. Deburred and primed the hole, then mounted the probe with nylon washers. Installed an Adel clamp for the probe's wire on a nearby rib so the wire will clear the large aileron pushrod. I ran the wire outboard through pre-existing plastic bushings to the wingtip rib, where it will connect to the Dynon remote compass.
