Hi all. 2009 f150 Supercab. I bought the blue oval camera and the mirror with LCD monitor off of eBay. Getting the front and rear wiring harnesses from Tasco. To put in the 16 pin wire harness for the rear view mirror i have to take the headliner down to pull out the 10 pin harness. Does anyone have explicate instructions on how to take the headliner down? it does not have to come completely down just the drivers side. thanks
