On the Titan XD 2016 there is a fairing on both sides of the 3rd brake light assembly. there are four 8 or 10mm bolts inside and there are NO holes and plugs. I had to gently pull back the headliner enough to snake a socket and extension in there. Poor design, no after thoughts.
Today i will try and pull up the assembly and remove it. It conflicts with my new camper shell and it has to go. Will store it for the eventual day in many years to come when i replace it to sell.
if the foam double-sided tape is difficult i will use a heat gun to soften it up and that should take care of it.
Anyone have any pictures or ideas on the 2016's???
