If you go through in the area where the police vehicles run the light bar cable adjacent to the C pillar there’s plenty of space between the headliner and roof. I just removed a cable as thick as my middle finger from that location, that went through the roof. Let me know if you need a picture to identify the location.Yeah thats what I was thinking. We use those all the time at work, i’d probably go crazy and add a bunch of Hondabond around the base because there’s nothing I despise more than water leaks. The only thing I worry about then is the wire bend above the headliner and then the MC4 bends below the solar module itself.
