Can anyone educated me on what this is and what it does ? I am working on replacing lines.

Those are your relays for your fuel pump and your knock sensor module. They are supposed to be mounted on the passenger side inner fender well .

The sensor on the far right is your MAP sensor that runs the boost gauge.

My advice is to replace both relays, one is for the fuel pump and the other is for the AC. Casper’s Electronics sells the replacements which have the female connectors w/ pigtail wires to solder to the existing harness.

Since it's upside down from left to right: Electronic spark control module (retards the timing when knock is sensed), AC Compressor relay, Fuel Pump Relay and MAP sensor.
