What is this plug???

I'm currently stripping down my stock harness on my 89 RS for an LT1 swap and I have no idea what this plug does/where the wires to it go. Is it an emissions deal? If so, can I take it out since I'm doing an all emissions delete? Its right to the right of the brake booster and to the left of the fuel pump relay. Thanks guys!

It's the ESC Electronic Spark Control module aka knock module.
