Yep, I pull off all of the loom, but waited till got to each branch before cutting it open
First I took all the wires out of the blue and red PCM connect that I was not going to use. Then one at a time pulled untill I had them back through the harness till It came to where the harness would branch off. then work on that branch untill the the unwanted wires pulled out with their pigtail. Taped that branch back up to keep it together. (check out all the orange tape on the harness) Then move on down to the next branch and so on. hope that made since.
I wish I had better pics of the harness before and after it was done, but I dont.
