Conversion to Toyota E-Locker
Hello Fellow Tacoma Junkies,
Have any of you taken a completely stock four wheel drive, well technically speaking two wheel drive, Tacoma or 4Runner and converted the stock rear end to a Toyota part-time E-Locker. I am curious as to how much is involved in this conversion. I have outlined the obvious steps below.
1. Find a Toyota E-Locker rear axle and rear differential with a gearing the same as your existing one so it matches the front differential.
2. Change out the ECU or Program the ECU to accommodate the intelligence involved in using the E-Locker.
Thank you in advance for all of your responses.

I have no idea why I'm bothering. Your posts annoy the hell out of me. You talk like you know things you really have no clue about. "ECU intelligence involved in using the E-locker". WTF? No. That's not how it works. Not even close. Has anybody here done it? For real? You did not just ask that question. 
Just click the link below and start doing your homework. Specific technical questions come later.

Next time try google first. Or at least post your newbie questions in the newbie forum. And stop talking like you know what you're talking about. Because you don't.

More than a few of us, in case you couldn't tell from above. 
And more than a few of us have done write-ups of varying usefulness and depth. The hardest part for me was finding a rear elocker axle (I did not choose to retrofit my existing diff) and then putting all the research of those write-ups and wiring diagrams together and modifying them to what I needed...in other words, not so bad. My donor did not match my original gearing so I found a front diff that did for cheaps. Your experience may vary.

Some 4Runners without a locking diff are supposedly pre-wired for it. A 1996 SR5, however, is not.
Seems like the general pattern is that a locker usually came with 4.30 gearing, and open diffs are usually 4.10. Exceptions exist though. So you're probably going to need to swap the front diff (shade-tree doable but more difficult than it seems at first glance) or changing the gearing in your new locker diff, which is not really shade-tree doable.
