I'm looking for a pic of how the upper O2 sensor wiring is routed. I have an LS3 and am considering installing Z06 manifolds, but the O2 sensor is farther downstream on the Z06 so the sensor won't reach without extensions or untaping wires. It looks like both engines use the same sensor, so I'm just wondering how it's done on the LS7 so maybe I can get some ideas. Thanks

Different wire harnesses. All you would need is a pair of o2 sensor extender harnesses.

Ok, I'd still like to see a pic for ideas though

Really not much to see. connect the extender harness the the oem connector near the coil packs, run the wiring towards the firewall and downward behind the engine and connect the the O2 sensor. Just make sure to secure the harnesses away from the exhaust and/or firesleeve as needed.

Does it clip to anything to keep it away from the exhaust?

I use wire ties to secure the extender harnesses away from the exhaust. Just double check the way you run the wires to make sure they are away from the cats.
