Can someone tell me where the low pressure switch is on a 96 S-10 4 cylinder? I can't find it but I might just be dumb.

Actually it would be dumb not to ask if you had to replace it and couldn't find it.

I don't know your motor at all, but look for 1 wire going to a sensor in the block. From what I've seen Chevy seems to like putting them close to the oil filter.
It can't be too hard to find, even if it isn't close to the oil filter
