I just need some info on splicing the LS1 O2 sims. Mine is a 2000 with a square plug, so what year LS1 sim do I need and also mine has 2 brown wires, so how do I know which one goes where and are the LS1 sims the same color wires? I want to get some cheap used ones from the car classifieds here if anyone could help. Thanks

 

I can't seem to get the right answer to that question either.
