I think the ESC module is inside the PCM in '93. My parts book doesn't show an ESC module for '91-'93. It does show one for '94-'95, plugs into PCM: 16177690
For the knock sensor, it shows two listings (I don't know what the difference is):
'92-'95 Y 5.7P (LT1): 10456126 AC Delco 213-96
'93-'96 Y : 10456287 AC Delco 213-325
I put in the AC Delco numbers because they're generally much easier to get and also much cheaper than the GM numbers.
