Question Stock lenght of O2 sensor wires, longest to shortest

I tried a search but came up empty handed....

I wish I had marked all my sensors before I pulled them all like two years ago....

Anyway, all the stock LS1 F-body O2 sensor wires seem to be a different lenght. I know that I was able to use one of them as a substitute for the right front after I put my headers in without needing an extension. I don't recall which it was though. I think I was then able to use another for the driver's side.

Does anyone have any info on the order of wire lenght (longest to shortest) of the stock sensors? Or at least any idea of which are the longest?

Thanks for any help.

I think rears were longer in some years, but I think for certain years they were all the same length. Curious why you're asking?

I was thinking that both of the rears were longer, but wasn't sure. Can anyone else confirm this? But of those two, which is longer? I wasn't aware that there was a difference between the years though. But I know for sure that on an '00 car they are different lenghts.

As for the reason, when I put my headers on 2+ years ago I pulled all the O2s out of the stock stuff and never marked which was from where. When I put the exhaust together, I just picked the O2s with wires that were the best lenght for the front (didn't use rear sensors) and it turned out that one was a perfect fit for the passenger side without using a O2 extension wire; it was the longest one of the bunch. Now I'm 99% sure that the O2 sensor that I used on the passenger side is not the one that came stock in that location, so I'm not sure which one I'd have to buy/order should I want to replace it.

From what I've been told. All the replacement sensors from GM for our cars are the same length. Only the stock factory stuff was "cut" to length.

Ah, I see. Thanks for the reply. Guess I'll have to use another O2 extension if the universal lenght doesn't fit....
