If you have tuned out the rear O2 sensors on you car I would like to have your pigtail and as much wire with it as you can get to. This is the four pin square pigtail that is on the engine harness down near the transmission and y pipe. I'm doing a little testing with the rear O2's so I need to hook them back up. Thanks and I will pay via paypal.

 

I have 2 LS1 02 extentions, i THINK they are the same as the rear LT1 wires. $40+ shipping, you do the research.
