( if the drawings are a little too crude or too jumbled together to understand, let me know and I'll redraw them. I'm in somewhat of a rush to finish)



I'm upgrading from my single stage to a 2-stage injection system. But I'm not 100% sure how to wire this. The pictures below show you how I currently have it now for the single stage, and an unfinished diagram of the two-stage system. The red marker is for fluid flow.

I don't want to add a second relay, but I will if I have to. I have a pretty good guess on how to do it by adding a second relay. But can this be done without doing that? And if you feel up to it, finishing out my diagram in paint or similar would be awesome.

I screwed up there. I used an old sketch and not what was on the car. That first sketch was indeed very wrong.

Mainly the NC port on the boost switch is NOT supposed to be used at all. Here is where I'm at currently. And differences on how I used the relay as well.
