Default LT header install

I need help with my pacesetter long tube header install. the headers are in every thing is hooked up but i don't know how and where the 02 sensors hook-up to? so i need to know what wires hook up to the 02's. just so you know i am in the process of putting a motor in so i am at the stage of wiring it all up. (car listed in sig) if i could get pics that would be great.

well since you have a 96 you have both front and rear o2 sensors, the fronts are just that, near the front, you will need to get some extensions, the drivers side might fit, mine was long enough but the pass side needs an extension(ls1speed has them), since on the headers the o2 sensors are near the y=pipe. For the rears you will need o2 sims or tune them out.

I just got finished with my install this weekend. The front O2 sensor connections are up near the motor mounts. I used the 24" on the drivers side and 12" on the pass side. I used zipties to hold them away from the headers. Got them straight from Casper electronics.

I have the PaceSetter LT's and have a custom 2 cat y-pipe and all 4 O2 sensors on mine. I was able to splice the back O2's in and haven't had any SES lights or any trouble for 2+ years now.

Yeah, I kept all four. I didn't use O2 sims or get rid of the cats.

2 in the collectors in front of the cats.
2 in the Y-Pipe after the cats.
