You Honda guy.... :bash::lmao:
Toyota calls it "VSC", same as VSA. '03-'07 (4wd) you must lock the center-diff to disable the VSC. Beginning with the '08 Toyota offered the switch you're looking for...
A "way better than nothing" solution can be had. It's a work-around and not perfect but by installing a switch that tricks the computer into thinking the center-diff is locked you can get the VSC off (without having to lock the center-diff). Click the VSC off mod link in my sig for more info.
