I was wondering if anyone knew how to fit a switch similar to the nissan pathfinder & x-trail have to switch between 2 & 4 wd. I basically want to be able to put the car into 4wd before it wants to as I found with the last rav I had (2000 same as the new one) that when we hit the sand the 4wd would kick in after the wheels started spinning, usually meaning that we were already bogged.
