Fitting a Toyota Electric Locker (E-locker) into 8 inch Differential

Toyota Electric Locker

From 1996 on, Toyota offered an option in there 4runners and Tacomas. It was a rear electric locking differential straight from the factory. Since the differentials use an 8 inch ring gear like Toyota mini trucks and 4runners (front and rear solid axles), the e-locker can be retrofitted into these axles.

This site has a great writeup of how to modify the axle housing to fit the e-locker, including comparison pictures between the e-locker axle housing and a standard 8 inch axle housing. At the bottom of the page is wiring information on how to wire the Toyota electric locker using relays.
