Clean 12v switched source that is hot cranking and running

The spliced IGN 1/2 wires trigger the relay at 86 pin, you can just pay attention to the second relay. Pulled fused power to pin 30 and out to EFI from pin 87. Wire pin 85 to ground and you’re complete.

I already have the power, ground and fuel pump wires for the EFI ran I am merely trying to get a “clean switched 12V source”
