I have two sentences making me confused.(1,2) I would be glad to know more about the below.
1.'Radar for fire control differs from ordinary radar chiefly in the precision with which it locates targets.'
What does "it" indicate in the sentence above? I'm thinking of "it" might indicate either "ordinary radar" or "the precision", but I'm not sure.
2. 'Seahorses have eyes that move independently of each other, which/that enable them to spot potential food.'
I'm not sure what should I choose between "which" and "that". Which word is correct?
If I get to know which or that should be used to indicate eyes, then I suppose it'll be okay to apply this usage when I refer to other organs such as bowel, stomach, tongue, etc.
Thank you in advance.

1. "It" refers to "radar for fire control."
2. I would use "which."
I know you have seen us ask people to post unrelated questions in separate threads. The question about the antecedant for "it" has absolutely nothing to do with the pronoun choice in the second question.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
