Dual stage injection on a single cylinder engine

[Vassili Wang]

Hello

What kind of wiring should I use on a Hi/Lo-injection single cylinder engine?

One option is: INJ1-Primary injector INJ2-Secondary injector

Another is: INJ1-Primary injector INJ5-Secondary injector

Which one should be used？

Thanks.
