Hello. I think I’m in the right section? Today I installed a uniden front facing dash camera in a 2016 Fiesta ST. I ran the wiring cable through the headliner. Started at the rear view mirror & ran the wiring cable to the left & down. I noticed the headliner has a slight gap in it. Enough of a gap that the wiring sometimes will fall out on the top section. Then has to be put back up. Does anyone know if there is any solution to this ? A way to securely hold the wiring in the headliner without it having the potential to fall out ? Thanks for any advice.
