mine is all secure and nice up there. tap for power in the blue wire in the interior temp sensor. ground to a bolt up in there. feed the wire thru the headliner to come out by where the rearview mounts. clean install. ive had mine there with the sensor right at/below the tint strip, and u cant see if i even have a rad. det. unless u look hard ar the glass. its the perfect spot. just play with it untill u like where it is.
