Hey guys, i've heard you can do this and I want to see if anyone has done it and can give me some advice. I have ESOF in a 2010 F350 with the upfitter switches. I would like to be able to engage 4 low while still being in 2 wheel drive (so I want the low gears but not the 4 wheel drive). Can this be done? What is the process?

 

interesting - would be perfect for backing the 5er into a tight spot ! subscribing

 

Member 175StroppeBaja has done a writeup on this mod to his 2004 F-250 with good pics and wiring daigrams. It's on my list too, hopefully this will help with the newer trucks too.
