I was just wondering, I have my MILs installed on my mac o/r h pipe and they are installed on the rear o2 sensors for the past few days, and my check engine light is still on. a few people on here told me that they belong on those o2 sensors. Do they go up by the headers, or back by the H?

In the back you have them in right, try unhooking neg from batery for 5 min and then see if it comes back.
