I have a 97 Z-28 and when I did my header install, I extended my O2 sensor harnesses myself, soldering and heat shrinking the wires. I believe I did an adequate job, but I could be wrong. At any rate, I'm thinking about replacing the harness and connectors and buying the pre-made extensions. I want to make sure that I'm getting the right stuff, so can you guys take a look at these and let me know if they're correct for my car?

as far as the extensions i think those look right its been a minute since ive actually looked at mine. as far as those pig tails why do you need those? you would just end up having to solder them like you did the other ones right? if they are working and running right id leave em alone with what you have already done but thats just my opinion. less connectors and pins ya gotta worry about going bad

and donno how true it is but i was told its better to use connectors on engine wiring cause of the vibrations n stuff. that the solder could possible break over time but i dont know for sure

For the front 02 sensors, you will want the 4-wire flat connectors. The rear 02 sensors used the square connectors.

Oh yeah, I forgot to mention that it's the front O2 sensors. So it looks like these are the right things. I suppose I will go ahead and buy them tomorrow.
