Yes it does, Spooky did that some time ago, I had a link when he posted it on the D3 site, a lot of intricate electrical work but a way to add the diff lock if you want to. was well thought out.
This makes very interesting reading.....

Yep, a lot of work.....I think I'll just order the e-diff on my D4 - a lot easier....
Or just fit a potentiometer (or switch) and make it a manual locker.
Sort of - I imagine you would need to change the entire diff/internals from standard to the e-diff - but that is basically what I meant.
It would be quick and easy to run completely seperate, manually controlled, wiring for the e-diff. You would just need to know the voltage needed to achieve a complete lock (which you could find using bench testing) - but presumably this would be 12V. Then buy a either a switch or suitable potentiometer to work it.
The computer won't know that an e-diff is fitted, and won't be able to control it, but it you can. The traction control system will just think that both wheels have the same amount of traction when the diff is fully locked.
Unlike the e-locker fitted to toyotas, the e-diff is not really a true locker, more an e-lsd.
Surely an aftermarket diff lock could be modified to fit in the diff housing. I guess it would be a matter of finding which one is the most suitable and having the skills and equipment to make it fit and work.
Here is chance for some enterprising individual.

						Given the integrated nature of the whole terrain response system I wonder what negative side affects you would achieve by tricking the trs into beliving that both back wheels are turning at the same speed? Thinking here activiation of the centre diff lock and perhaps something when the steering wheel is turned which would cause the system to expect the back wheels to turn at different speeds and thus triggering some sort of unwanted intervention.
