can i install the rear system to lock the differential

Hello, I do own a Toyota Hilux, and I've seening Tacomas, Fjcruisers have a swithc in the cabin that allow locking rear differential OEM. Wich parts numbers are these functions, and what do you think about installing this onto my 10' Hilux.
thank you.

 

You're gonna have to replace the whole rear end, I believe, and do some wiring. Better to go with an aftermarket locker, like an ARB or such imo.

 

I would just get an ARB air locker. It'll probably end up the same or cheaper than an E-locker. I did the E-locker swap and it was free for me only because I found a wrecked 06 Tacoma that I pulled it out of and then resold. Also, the 8.4 diff will be stronger than the 8.0 E-locker one.

 

Concur with the ARB locker.
