I have a couple of Scan Strut roof entries and i'd like to run a pair of 10 ga. wires and my 2-way antenna coax through the roof in these. I am not quite sure on pulling down the headliner in the rear cargo area though. I pulled back some trim in the rear door area, but wasn't able to figure out how to get the headline down even a little. I didn't want to blindly force it. I couldn't find anything in the FSM nor online that was clear on how to pull the headliner down a bit. Everything i've found is either a later model or something do with more forward in the cab. Do I just pull hard? Pop some hidden clips? I'm running the cables in near the rear passenger factory roof rack mount and down into the rear passenger quarter panel. TIA.
