That would be helpful as the fuse box is back there and the battery for those who are looking to hardwire. I’m curious though about routing the wire from the top of the windshield to the A pillar and down. In my x1/x3 and m240i I could tuck into the headliner and the A pillar cover pulled out and off. The z4 A pillar looks to be snapped in place down the sides, but 2 potential screws on top. One looks like it’s the screw for the sun visor, but the other looks like it’s under the center plastic cover (all of this is referenced from the pictures on realoem).
