Okay here it is. Take 2 trunk soleniods and a little imagination and whala...



I'm not quite finished, I'm not finished with the cables and there needs to be a return spring added to pull the ports closed.



This is connected to my Haltech and triggered at the RPM level I choose, but could also be a RPM switch.



They are either fully open or fully closed, there is no in between.



The Soleniods are bolted with the supplied hardware to the AFC <?? I think that's what it's called. The brackets (strapping) you see is used as a place to connect the return springs to.

How well do you think they'll hold up to the heat?
