93' to 96' conversion....NO SPARK....HELP!!

I put a 96' harness on my 93' camaro, a mass air, and a 94' PCM. The car now has no spark. Everything checks out as far as the signal going to the ignition module, but still no spark. I swapped coil and ignition module to 96' also. Everything is plugged in also.

Anyone ever ran into this?? Any ideas/suggestions?

Thanks in advance!

So why am I not getting spark?? I've changed all the sensors, connectors etc. etc.

But no spark.....signal is going to the ign. module no problem, where am I losing it?

Did you swap the wires in the connectors going to the interior harness?

What exactly needs to be swapped in the interior harness?? Everything plugged in, no problem.

Ok, but how would that cut spark?? What does the interior harness control?

I don't mean to sound rude or anything, but in that post, I said that the wires are in different spots and need to be switched around. The interior harness has a lot to do with it. That's where your ignition, vats, etc wires are going through.

http://shbox.com/1/harness_connector_faces.htm

click 220 on the bottom of that page and compare 93 and 96.

same goes for 100 and 96s also have an extra connector going to the forward lamp harness which you will need to sort out, because 93s don't have it. It's all on that page.

Is 220 the only one that needs to be changed?? Can you push out the pins, or do you have to solder the wires?? Are all the wires needed already in the 93' harness, or will I need to run wires from the PCM?

I figured out the C220 connector, but what do I do with the C100 connector?? It has a few injector pins I'm not sure how to correct.....anyone done this or know which ones to move where?
