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

Meaning the starter does not engage? If so, you need to check the wiring from the ignition switch to the starter solenoid.

Also, I can be wrong (have to dig out my LS swap books), but I think the ECU (99) is not compatible to the later year engine due to different crank position sensor (24 tooth vs 58 tooth).

The starter turns over but will not hit a lick. The fuel pump and relays keep clicking. If I unplug the tac module it will fire up but no throttle then and as soon as you plug it back up something happens
