Hey guys, I am trying to scope out how I am going to run my wiring from the head unit to the trunk. I've been able to pop off the side sills and kicker panels to run the wire underneath them. But I am not sure how to run the wiring into the trunk from the rear side sills. There is that thin plastic pillar on the side of the rear seats, I tried taking that off but I could only pop off the base. I believe if I am able to pop that off I can run the wires around and into the trunk, I just don't want to break anything before I know it can come off. I have attached some photos for reference, I really appreciate your help!
