OK, I'm not new to Toyotas but I am new to FJs; can someone explain how to get ATRAC on a base model FJ? All I've been able to find is that if you get the locker, you can buy a switch and have the ATRAC, too? Can someone explain further? I'll go buy one tomorrow if that's true! (Well, I'll buy one on April 3rd - I can explain later) Thanks.
