Thread: Will a post cat O2 wire harness spliced into the upstream O2 sensor wire harness wk

I have read a lot about speed daddy headers so I picked up a pair and a new longer cabled O2 sensor (for over $50) from advanced auto since that was the best I could find locally. But yesterday I went to the junkyard and for 6 dollars I got an O2 sensor but the upstream one needed was too hard to get to so I pulled the downstream sensor and wire harness. I’m sure the wire gauge is the same so I can do a solder and heat shrink connection but I would like to do as little as possible to make it work. What does everyone think? For $6, 20 min, plus a hammer, 7/8 wrench and a knife, this seems like a good deal to me.

I picked one of those up in case the junkyard setup does not work. Thanks for the help. I had read bluegtp had the info on the extender but I could not find the site.
