Wish I was closer. I'd like to see this for myself. I do believe you are the first we've seen with no power to the ICM without the fuse being blown.
Below is a picture of the ICM wiring harness. The wire we want to check is the pink with black stripe on the left hand side. If this is what you checked then we need to see if power is getting to the fuse. Remove fuse #6 & check for power at both terminals for the fuse. One side should have 12 volts. Ground the black meter probe then touch the red meter probe to each of the fuse terminals. Let us know what you find.
