RR diff lock on my 2.7L 4x4 2010?

Hy,
I'm new here, I lived in Quebec(Canada), I just by a tacoma 10 SR5 4x4 2.7L and I would like to know if I can put a functional RR diff lock switch on it. Thanks for answering.
I talk french but I understand english very well

 

Je parle un peu de francais...j'ai étudié cinq ans. Bonne chance!

 

Gona put one in mine

 

If you do the wire mod, which is very effective, you might not need this...

Do a search on the wire mod.

 

i did the wire mod on mine.
it's a lot better than stock but a locker would still be better if you are wheeling alot

looks like this is the thread for the Yellow Wire Mod.
