Hey there, I've only just joined this site, I also have a 2011 glxr.
I am wanting to run a dual battery system from under the bonnet.
However, I am kind of stumped with the ASC A an B box mounted at the back of the engine bay where the dual battery tray is suppose to mount. What did you do about this when you installed your batteries? I've had it suggested to move it as close to the wheel guard and fuel filter as possible.
