Hi everyone, first post! Just joined up from the UK ? I have just completed hard wiring the fuel pump following this guide (was a massive help so thank you for that!!) Only part I am unsure of and can’t see here.... The earth wire you cut, the pump side goes to the chassis as instructed, but what about the harness side from the controller?? Do I need to ground this or leave it unconnected and cover it?
