Okay, I dig the sound of this, I just want a little clarification. You CAN put the switch into either of the wires coming from the transfer case. After doing so, and by leaving the switch "ON" (all connections made) you can drive and shift the truck the same as always. If you flip the switch while in 4 low, it will disconnect the front and allow 2 low? You probably just want to put it back "on" before disengaing the 4 wheel, so that you can start as normal next time.
