Default 1994 Z28 engine in 1996 Z28 body

So I put a 1994 Z28 motor in a 1996 Z28 body, using the 1994 computer and engine harness. I went to turn the car over and nothing happening, as in it seems the vats system kicks in. I went to change security box from the 94 to 96 but you can’t because the vats in the 96, are inside the body control module. which is understandable. I know you’re supposed to move C105 pink wire so I just made it touch a positive post hoping it does something Lol. Also to mention I used the steering column from the 1994 because it had a different cut key, without a “vats resistor” in it. I’m not sure what to do here.
Any help appreciated

You might be able to use a remote starter switch to at least get it running. I know this worked on mine. But there's a chance the injectors are shut off. Worth a try,

car turns over now, but not getting the injectors to fire, and I don’t think I’ve got spark as I put gas down the intake, and no coughing or sign or firing.
