HFS-3 'box/control unit' sending voltage out the green wire, HELP.

[The Alchemist]

So I have a HFS-3 unit from Howerton and it's been on my 2000 trans am for a couple years now. After this winters rebuild to a bigger motor and bigger blower, I've recently been chasing a P0200 code, which is injector malfunction.

Long story short, I checked all the voltage at the injector connectors and found 10-11v on the #1 signal wire with key on/engine off. I traced it back to the pcm, and found the Aquamist green wire is tapped to that injector signal wire. So I removed the green Aquamist wire, and sure enough, it has voltage going to it. I checked the continuity and it checked out fine. Next I disconnected that harness from the controller box and checked again, and there is no voltage. Checked the box itself, and sure enough, it is sending the voltage to the green wire.

I'm guessing the controller box is bad and I need to have it repaired.

Any help is appreciated.

Thanks.
