Your Darts $ hitty BFG tires were the issue there... they are like plastic power wheels tires in snow.. i have personal experience there.
Funny how I daily 'd a Detroit locker equipped stock otherwise Gmc pickup through snow and ice most on this site can't even fathom and never had a problem in 2wd.. in fact that locker was the best thing I ever did to that truck for these highways. And even more curious is that same truck now in the hands of my 20 year old female apprentice still has no issues with winter roads in 2wd. People need to understand that even Fords own oem clutch pack limited slip will mimic the action of a locker on a surface with a friction coefficient approaching zero. In her case the Dodge Ram she owns also has the factory Auburn cone gear limited slip in it and she finds driving my truck absolutely no different than her own on snow and ice. Nice thing with a locker... if even one of the two finds traction you stay in a straight line because the tire on the more slippery surface doesn't do the one tire fire and sway the rear end.
I too want to lock my F150 ' s diff when I desire. I may try and make the Raptor TCCM thing work for me though. I know guys tried and failed with the off road function before.... but my difference is both my trucks have the Raptors powertrain anyway... so maybe I can make it work. Killing that retarded Advance trac and roll stability control are a must. If not... the op ' s method for the locker and toggling power to fuse 47 will do the trick.

I was a bit off on my memory the 8.8" in 2012 is listed as only coming in 3.55:1 and 3.73:1 ratios.
Page 9 of 15 in the reference listed below is for Regular Cab 4X4 with the 3800lb rear axle max weight and Ford says it comes with the 8.8" in the rear. So if the 4x4 with 3800lbs is the 8.8" I would still wager a guess that the 2wd with 3500lb rear axle is also the 8.8".

Either all that or Ford doesn't know what they are talking about
