You have two options in order to eliminate the SES light. You can buy a "handheld tuner"(SCT, Diablosport, etc) and use an option to tell the computer to ignore the rear oxygen sensors. Or you can purchase some harnesses call "MIL Eliminators" which you will have to plug into your existing rear 02 harnesses.
for tuners. These are SCT tuners that are branded "Bama" by American Muscle. They are still the exact same tuner. There are advantages and disadvantages to both SCT and Diablo. SCT is more widely used and much more widely supported by custom tuning shops.
for MIL Eliminators. They are pretty self explanatory.
I use my handheld tuner to shut off my rear oxygen sensors. I am in NC. This works fine for the computer side of the inspection but shops will visually look for cats too in NC. Without that friend shops will still fail you if they do their job and look for cats. I have become pretty slick with talking my way into getting people to pass my car when it fails but its really annoying.
