02 sims question
hey everyone, i am new to the site. i just bought pacesetter headers and a catted y-pipe from texas speed. i also got o2 sims and extensions. my question is where do the rear o2s go. i cannot figure out where they go i would have guessed that they go after the cats on the y-pipe, but there are not any holes or anything. any help would be appreciated.
thanks
thanks

they plug in to where the rear o2s plugged in at. they dont go anywhere on the y-pipe. thats why they are SIMulators. they only simulate the rear o2 signals the PCM would be looking for. since you have cats, you'll have to get bungs welded on the pipe in order to use the rear o2s, or you could just run the sims. the PCM wont know the difference.

Just get your rear O2's deleted with ls1edit or any other of the tuning programs. Sims may or may not work. Get used to your SES light coming on if they don't work.
