Have you checked for voltage on the feed lead?
The other lead is the ground pulse from the computer. If you see it pulsing a ground with an ohm meter it's good.
I don't think a computer sub will work by not allowing you to start the motor if the truck has theft option due to programming differences.
The electronic dash 'marries' the PCM. If they don't match, no start.
Good luck.
