Nitrous keep around 12.0-12.3 for safety you can run some as lean as 12.5 range but why risk it. Need to also lower spark a tad under WOT

The power for both ignition coils and fuel injectors come from a common source, ASD relay. The color for a 05 is BR/WT. On your year it will be the wire that is the same color on all coils and injectors. You can solder a splice for a trigger or use a MSD tap that doesn't damage the wire.
