PS belt position

[1983cucv]

I have removed the drivers side alt for reference.

I have a PS pump with a two groove pulley and I'm not sure which groove I should use. The back groove lines up with the smaller crank pulley (rear) and the front groove lines up with the larger (middle) crank pulley. Would the middle (larger) crank pulley spin my PS pump faster than the smaller rear pulley?

Thanks.

Which groove is the correct one to use the smaller or larger one? If I spin my PS pump too fast will I burn it out?

the PS pump uses the second pulley on the crank. the third pulley is used by both the drivers side alternator and the PS pump.
