I just was given an Underdrive Pulley kit (dont tell me it aint worth cause I got this for free)

But anyways, here I have two pullies one large one and a small one,
But yet I cant figure out which one is which cause there aint no instructions...

My guess the smaller Pulley would be the Power Steering Pulley??

So which one is it?

 

well, in my integra gs-r the power steering pulley was right behind the driver side headlight. hope that helps.

 

For my AEM pulley kit, the bigger one was for the power steering and the smaller one for the alternator.
