Preparing to wire a 5.9l Magnum into my Barracuda..
In order to have the engine running,do I just need to attach a 12V supply to the igniton feed on the PCM ?No,9 pin.....I figured that all I need is a power supply to the mudule and hook the rest to the engine have it running? am I wrong ?

For the MAP (5volts output)and distributor (8volts output)is the PCM dropping the voltage or do I need a relay to provide 5-8 volts to the computer on these pins ?
THe pcm comes from a B350 Van (AB body)
I kept the 904 trans(beefed up), the alt circuit, starter relay etc... from the Barracuda

Thanks for all the help
