Using 806-155 instead of MAP sensor?

[rukman]

With regard to the HFS-3 and/or HFS6

can one use the 806-155 to active injection based on a specific pressure?

if 806-155 is normally open and closes when desired pressure is reached can this be wired to the blue wire on grey harness for the MAP sensor?

therefore on HFS3
Move jumper to inject based on MPS
Adjust THRES ADJ trimmer all the way counter-clockwise.
When 806-155 closes it would trigger injection based on IDC.

can this work?
would 806-155 have to be wired to a 5V or 12V signal?

please advise...

thank you!
