It is as simple as buying the $60 A-TRAC switch from your friendly Toyota dealer and installing it to the dashboard. All of the hardware is already there, it is the same stuff used with the regular old-fashioned TRAC that comes on every FJ Cruiser. I am sure it will work on the ones with the rear locker but not positive about the base models without the locker as the TRAC ECU has different part #s for w/locker and without and ATRAC is not offered as a factory option without the rear locker. If you are not sure about spending the money you can also install a single pole momentary switch to the pink/green and black/white wires at pins 3 & 4 of the Active Trac control switch connector.
Methinks it is possible to order an FJ with the locker as the only option purchased, buy the switch and have a decent rockcrawler for under $25k.

You cannot add A-TRAC to an FJ Cruiser that did not come from the factory with the locking rear differential. See posts by PRCruiser and gunther here:
