Wrong O2 sims for 2004
Just ordered a set of rear O2 sims from Speed Inc. for my friends 04 Z and they don't fit. 
Keyed different. Does anybody have an 04 that has the simulators? If you do, please chime in. 
Thanks, Frank

I went through this quite a while back so my memory is fuzzy. But I believe that up until 2004 the front and rear sensors were the same. However in 2004 they started using different front and rear sensors.
How do I know this?
Well, we discovered this during an LG header install where the new cats are in the back instead of the front. Normally when doing an LG install the rear sensors, (because they have longer pig tails) are moved to the front harness. That won't work for a 2004 because of the sensor differences. So.... when you order a sensor for a 2004 you need to specify which one you want, front or rear.
