I googled and found how to take apart the a pillers. There was a British or AU site if I remember right. I ended up mangling my clips pretty good.
. I don't remember reinstalling the a pallet being difficult once I figured out how it came off.
The worst part is trying to get the wire ran and covered by the headliner. I spent a while cursing trying to push the wire under the headliner and got most of it. I couldn't find a good diy on how to take that down. If I wasn't so cheap, I would have paid the dealer to do it right with the right tools.
I can't deny the awesomeness of this upgrade though. Definitely a high class upgrade.
