Yup, like I did... Find the purple wire w/ yellow tracer under your truck. It will be on the driverside frame rail. DON'T Cut the wire, but splice into it with a splice connector. Run another wire up to a switch and the other side to ground. Flip switch = Locked TC. Thats how i have mine setup.

Yep, that's it. There is 12V on one side of all the solenoid coils, the computer grounds them to engage.
I'm sure you've heard all the warnings about when to no use it. If not.... research it.

So, does this give you a mpg increase? What is the risk if you fail to unlock before you try to stop?

Might see an MPG increase?? All this does is let you decide when to lock/unlock the TC instead of the PCM. If you forget to unlock it before coming to a complete stop the engine will die...kinda like coming to a stop with a manual trans and forget to push in the clutch.

And I thought that the engine stall would be the case, but my concern was the possibility of damage to the TC/Trans if you stopped while locked...

I don't think stalling the engine would cause damage to the TC or trans but you never know. I'd bet after a few stalls you would learn not to do it

Thanks gentlemen, pretty much answers my questions...
