2004 Monte Carlo Ls l64 swap icm issues
 

I swapped my running 3400 for the l67 from a 02 ssei. I used a 02 mc ss wiring harness. Tried to use 02 ss pcm. No security light no crank. Tried a 03 gtp pcm same thing. I plan on buying an pcm to work with my car. Back to problem at hand I figured out it was a no spark issue. Tested the pink wire at the icm and it is reading as a ground. Went to test ground and I'm getting nothing there. So my question is, is the wiring for the pcm different I have checked the fuse that it runs off of and it is getting 12v
