No spark/fuel

Car is a 94 camaro z28 bought as a roller. Engine, trans, and harness are from a 95 trans am. Everything worked while engine was in the trans am. Put everything into the camaro and now I am getting no spark, or fuel. I seem to not be getting power to the pcm (all grounds are good). Engine harness has both c100 and c105 connectors, but the cars body harness does not seem to have the c105 connector, as pictured. As I understand it, c105 has a wire thats involved with the ignition switch. Is this my issue? And if so, what is the easiest way to fix it? I still have the 95 trans am, should I take the body harness wires from it, and transfer to the camaro, or is there an easier way?

You need to use the 94 engine harness, if you need one I have a spare for a auto 94

I have the harness that came with the car, I assume it's the stock 94 harness. It has a few pigtails cut off but I can cut the pigtails I need off the 95 harness I suppose. Being that I'm using a 95 trans, won't I have to run an extra wire to the trans for the tcc solenoid?

Also, why do I have to use the 94 harness? I've had a 94 before and it had both the c100 and c105 connections?

As you may have suspected, the 94 has no C105. On the 95, C105 is mostly used for the traction control, cruise control, half of the injectors power, and the ALDL communication wire. I don't see anything about power to the pcm on that connector. You probably will have to look elsewhere for that problem. You can jumper the pink wire at C105 pin B to the pink wire at C100 pin K (only used for the V6 engine) to get the rest of the injectors power. But first, make sure there is no wire at one side of C100 pin K on the engine harness.

I think itd be easier to run 1 wire than repin connectors. Just my opinion. When i went 94 drivetrain into my 96 it was easy, just use 96 engine harness and coil.

Okay, got started on splicing the cutoff wires back into the original 94 harness. All plugs are there, except I've traced about a foot back and there are no wires in the 94 harness for the ICM..
