Australian (RH Drive) Stock standard LS trim ZH with no optional extras (ex state govt vehicle)
I have sourced and installed Bluetooth module (installed behind the radio replacing the USB only module), microphone behind front map lights and new steering wheel with the phone controls.
I have sourced and installed the fog lights with the combination stalk control.
I have sourced and installed the "Chiller box" vent control and air hose.

I am looking for a good space to install a dual battery set-up, not enough room in the engine bay
******** Any helpful advice and, particularly, detailed work instructions on physically doing the above is welcome. I have NO IDEA how to get into the cargo area floor.
