The trunk shots are to show you fitment of my MDF false trunk floor. The middle hex screw secures the bottle bracket to the board, the top hex is the long screw connecting down to the spare mount (under the board). Additionally under the board and mounted to the back wall is a 40/60amp relay and my progressive controller "brain". Most wiring travels under the carpet and thru driver\passgr kick plate trim edging.

Remote bottle momentary switch is on the plastic panel home to the fuse box. I chose that location cuz there is empty room in there, and again if I wanted to revert to stock I just need a new cheap panel. Solenoid wiring runs under the rubber passthru grommet to a relay in the batt pod area. Easy 12V feed to relay and switch panel wiring running thru a wire loom grommet around where passenger windshield meets dash.

Switch command center is where my OEM nav used to be. Fabbed an aluminum backplate, powdercoated wrinkle black and went with Dorman 30amp toggles. NAV keyboard was popped of buttons\joystick and wrapped. Dynotune pressure gauge is 3M taped to side for easy removal.

My ultimate goal was to limit any permanent alterations to the dash and such to give me the option to revert to stock look. I didn't care about the OEM NAV as it is dated technology and I went double din headunit that is better NAV.
