need advice for this setup

[goob8869]

Can you tell me if this setup will work or not. I have a 67 Camaro with a 05 Cadillac CTSv ls6 in it, but the harness and ecm are for a 99 corvette. The tach mudule, dbw pedal, and throttle bodies are from the Cadillac. I have replaced the tach module, pedal, and ecm but the car will still not crank
