Front o2s mix fuel, rear check cat function. You will need to trick the rear o2, tune it out or get sims. I highly recommend tuning them out, and tricking them until you get them tuned out. Sims are about $70 or more, and can fail or not work on some cars. There are threads across the LS1 forums about failed sims.
    I would like to eventually get them tuned out but is that required right away? Wont it just throw the SES light on and that's it? If I don't "trick" them will it hurt my car in anyway? Thanks for your help.

    IMO, you need two 12" o2 extensions. I re-routed my drivers side primary wire to get it away from the header so I had extra wire to begin with, so the 24" was just too long.
