I just got this truck about 2 weeks ago and have a question about the rear locker. On my last truck, a Tacoma, it too had a rear locker. It would engage with a push of a button but I had to be in 4 Lo for that to work unless I did the rear locker mod on the truck. On this truck, my local dealer pulled up all of the truck specs by the VIN number and confirmed it does have a rear locker but I see no button to engage it. I'm assuming it does it automatically then when it detects it is needed. So now I am wondering if it also only does it in 4 Lo or 2 Hi and 4 Hi as well and if there is any type of mod out there that will also allow me to engage it whenever I want too?
