When we were out at Jamboree with the TRD Pro, I noticed one open area between the windshield washer fluid inlet and the fuze box on the driver's side. In between them is a module labeled Toyota 89z15-930bc. I googled that term and nothing came up yet (not surprised). But the point is that this module looks like it will be easily relocated, either pushed back to one side or titled back so that it doesn't take up so much vertical space. Even if this module can't be relocated, there is plenty of room between the module and the fuse box allowing for switch panel trays or maybe even a small compressor like the ARB single. Outside of this location, there really arent many other options for switch tray/compressor mount locations on the new 6th Gen.
