Mounting studs in engine compartment

OK, this may be a dumb question but I can't seem to find an answer anywhere (at least with the keywords that make sense to me). On the passenger side, near the firewall, there is a mounting bracket with three studs. What accessory goes here or what is mounted there on a different model? I have a V6, 4X4, TRD Off Road package.

Curiousity more than anything... (Though it's hard for me to believe that this hasn't been wondered by many an owner)

 

welcome to TW too!

 

On the 2005 and 2006 (probably other years too) Tacomas the ABS motor was mounted there. Then on later models they moved it to the drivers side.

 

2007 4x4 TRD v6 off road package, My ABS Motor is there.

 

I have the same studs on my '08.........

 

I'll get a picture up eventually but sounds like legacy ABS mount... That's all the inquiring mind wanted...
