Fuel pump relay mod and rewire Skyline R33

After fitting a Walbro pump the car was running lean and I had to replace the fuel pump wires with thicker ones. This details how I did the wiring and what spares were needed. A big thank you to the SAU community forum who helped troubleshoot and gave great advice.
