GEN 2 Can't lock rear Diff in 2H?

All we need to do is apply voltage to the locker from a relay controlled by one of the handy up fitter switches and we can bypass the computer.

Until it's been done, it's just theory. The idea seems sound, but today's electronics are not always that simple.

What if the PCM requires a secondary algorithmic input to avoid throwing a code and sending the truck into limp-mode?

Worked fine on my Rubicon.

I honestly don't believe they put that kind of effort into it. The locker just needs voltage.

Maybe. But considering the electronics in the drive modes control if it can be turned on or off, it might be a little more complicated than that. Until someone is successful, it's still just theory. I'm not discouraging the idea, just trying to keep the ideas coming. I hope that with the collective knowledge that we will see in this thread that a solution can be found.

I'd be willing to bet that you're right and the locker is integrated into the TC system somehow. It might be doable, but it probably won't be a simple one or two wire fix.

Yes, One Wheel Spin Control. It will even do it with the front wheels when in 4wd.

Interesting! I wonder if that's why they set the truck up to not allow the diff lock in 2wd. Maybe it cuts down on warranty repairs and still gives you the characteristics of a lsd at least.

I'm guessing they were sick of issuing 34 spline axles under warranty to guys running it locked on high grip surfaces.

Where's 17Jake? Get him to unplug the weather pack and apply voltage. This is something that could be tested in fifteen minutes, it's not rocket science.

Thanks HK, the positive is that everything performance with Ford is now under one umbrella. The name Ford Performance, there are many benefits to this one being quality and performance.
GOOD NEWS!! I called FP this am 12/16/2016 and was informed that they are working on a tune that can be bought/installed by dealer for the 2017 Raptor. The rep said "the tune will be available very soon, not later."

Does the tune activate the locker in 2H?

All those saying to just apply voltage to it to lock well you would be WRONG.. You will burn it up.

Now Walter Burch has a unit for the Gen 1 that has the correct voltage to enable the locker outside of the Vehicle controls and I bet it can be setup for the Gen 2 as well. Just need to look at the connectors and wiring to make sure its the same setup. Seems it is even more useful with the Gen2.

I have to have 2WD and Locker action as its my favorite way to run at SnoBall and in the sand.
