Rewire lockers 2005 Dodge Power Wagon

I need help! Does anyone know how to rewire the lockers on a 2005 Power Wagon so that I can lock it up in high range. Low range is just to low in most areas that I go. I know that this is not to be used on the highway and at high speeds.

Thanks in Advance
Note: I had this done on my 2004 Jeep Rubicon and it works very well, but wagon is wired differently.
