The physical changes made to incorporate this case into the Tundra include swapping the rear output flange, swapping some parts from the Tundra transfer case 2WD - 4WD actuator into the Land Cruiser AWD - CDL actuator.... and last are some simple mods to the front differential disconnect actuator that allows it to function while keeping the fork that locks the coupling sleeve to remain in the locked position. No wires or ecu's need to be bothered with.
Exactly one custom part is required, that is a small spacer that holds the front diff actuator shift fork in the locked position on the shaft which it normally slides on. Over the weekend I will snap some pictures and write up some basic instructions on the mods required.
The truck is an absolute blast now... the street manners are much improved in normal driving with the front end pulling a bit. Recomended....

Is it safe to assume by AWD that in a slip situation, you maintain an electronic limited slip (via braking) in the rear, and there's an open diff in the front?
I've been stuck in soft sand before: in 4LO each wheel spins approximately 1/2 turn, then the brake stops that wheel from spinning and so the next wheel takes over. Surprisingly, this was a very effective mechanism and I slowly walked the truck forward despite the very low grip situation.
