rr diff lock 2002 4x4 tacoma

I noticed the light "rr diff lock" on the dash of my 1st gen Tacoma but I do not now how to engage it and if there is a switch or button I do not know where it is. Can you lock the rear diff on a first gen and if you can, how? thank you!

 

If yours isn't a TRD Off Road then it won't have a locker, it's just a blank spot on the gauges.

The first way to know if you have a locker is to look for these...

The switch






The locker motor on the axle...





If you have these, then you have a locker, and to engage just hit the button when your going under 5 mph. The light in the gauges will blink until it engages. Do not go over 5mph until the light turns solid. Do wide s-turns forward and reverse if it doesn't want to lock. don't turn too tight or it can bind...

 

okay thank you for the help

 

Oh, also. If you're 4x4 you must be in 4-low to activate the locker, unless you do what's called the "grey wire" mod which allows you to engage it in 2 wheel drive and 4-high.
