Took pants off of brackets today to have a look. I think thy're a little too light on the epoxy so I mixed more and set them up again. Move over to the wings, Installed the OAT sensor on the left wing. Torques nut to 90 in/lbs per Garmin G3X installation manual. Inserted GMU22 into bracket, connected it and secured wiring. Got out the landing and taxi lights but need to understand the wiring before installing them.
