Code 43 on 97 Chevy 1500c 5.7

What is your question?

I know it's the electronic knock sensor, but it's all rusted and can't get it out also there's no wire? And don't know where to connect it to (the wire) when I get one, can you help me out? Also where is the esc module? Any help will be appreciated! Thanks!

What makes this problem better or worse?

Starts, rough idle, then dies
