How Do I Bury Dash Cam Wire in Headliner?
Recently bought a dash cam and I’d like to mount it fairly permanently near the rear view mirror with 3M adhesive. To make the install look as good as possible, I want to bury the power wire out of sight. I’ve figured out the A-pillar trim can be pulled away fairly easily because it’s only held on with Christmas tree fasteners and the panel below that is a screw and two more trees, but I’m afraid of breaking the headliner. I tried just pushing the USB cable into the small gap between the headliner and the roof, but the headliner didn’t seem to want to move away and let the wire in. Is there any sort of fastening on that leading edge that’s preventing the wire from sliding between the layers? Is the headliner made out of something so stiff that if I force the wire in, the stiff backer might crack or break? I honestly don’t know what holds it up and from where, so if someone else has buried a radar detector or dash cam power wire in the headliner, let me know so I can either uninstall the front edge correctly or stop being such a wimp and force the wire in. Thanks!
