According to GM Shop Manual, it should be a CS-130D generator. The regulator has four terminals, P, L, I, and S. The P, I, and S terminals are not used. The L terminal provides an input to the instrument cluster for the charging indicator and voltmeter.

Can this be interchanged with a P-L-F-S regulator since only the L is used and the others three are not?
