Turbo 383 in a A-body Barracuda

Ok, wish I was there. It would be easier to diagnose. Im trying......

So you wired it like the first picture I posted. So it is + triggered off your ignition switch at cranking.... I would check that wire when cranking again. I bet it shuts down and looses +12V.

Where are you pulling the MAIN + and Neg leads from?

Lol! I thank you for try'n! My scalp hurts from scratching so much.

Its wired just like the first pic.

I did however have the trigger/switched 12+ hooked into the acessory teriminal on the back of the fusebox and when I turn the key it died. I removed it and provided a constant 12+ to troubleshoot.

Main 12+ is direct to the battery side of the starter relay under the hood.
Checked main power and its there even while turning key. I built a new harness with fuses at the battery and 30 amp breakers just above the FP controller and MSD's. They each have their own circuit.

Negative is bolted between the lower dash mount and A-pillar with clean metal.

I'm tempted to swipe the 6AL out of my Dads Duster! Its old but still works.
