Turbo 383 in a A-body Barracuda

Sounds like it is right. Check the MAIN power wires for +12V.....

Also I am betting the White Wire that says do not use on the BTM will ultimately need to be connected to the Original NEGATIVE Coil Wire from your cars harness. How else will it know what to do, there is no feed for the ignition signal that I can see the way they say to do it.........

The white wire on the BTM has power when tested with a test light. It is not wired to anything per instructions.
