I'm in the market for a Tacoma and found one I am going to try to get but I havent had a chance to look at it in person yet. From these pics does it look like this one was optioned with a locker? My main clues were the button on the left of the wheel and it vaguely looks like the diff drain is on the driver side...

 

It looks like a clutch start cancel button..not a rear locker button.

 

See that blank piece just to the right of your dash dimmers? That's where the "RR Diff Lock" button would go mmmmkay?

 

no locker on that one. I'd hold out for one, if i were you. It's worth it.

 

look for a real trd one it will have a locker

 

thats got a pass side diff plug = non trd = no locker
