Red ring goes to positive battery. Black goes to negative. Yellow stay unconnected and the other two splice into the factory line to the pump. If I recall its the pink wire on the harness. I can't remember off the top of my head which color goes to the pump side and which goes to the ECU harness side. Locate the relay in the battery box same as the Exa pump and run the two long wires back to the fuel pump.
There was a rough sketch in the other BP thread showing how to do it.
