That is my fear as well, I always put a microfiber towel on the windshield if I'm connected especially since it is connected on the passenger side. Just to add more clarity, in my previous car I had two access panels in the trunk where I mounted a ctek (56-380) indicator panel on one access panel, then took other access panel off and dropped ctek 8' extension cable thru and down to the ground, then closed the trunk. The battery was in the back near trunk (mid engine). I will try to figure out if i can get something rigged to the front in one of the vents or something. Currently I have it running up thru windshield "gutter"
