Do I need to relay my fuel pump?

Putting in an LS3. The harness instructions say "The fuel pump is controlled by the ECM. The control wire supplies 12 V and is fused/relayed and should connect to the 12 V side of the fuel pump using 10 gauge wire (minimum size)." So it's already relayed and I just run a wire from it to the pump right?

What harness are you using?

The GM Performance Harness has the Fuel Pump Relay included in the Fuse Box. If so then run the designated wire to the pump.

If you are using a stock modified harness or custom harness it may or may not have the fuel pump relay built into it.
