Color code placement for upstream O2 sensor connector
Hey guys i need some help here, i bought a 2010 camaro from a kid who was bracket racing it at our local track in Springfield Misouri. Brought it home and found a bunch of issues. Got most worked out but when i drove 500 miles round trip to KC for a dyno tune I found out my 2 front/ upstream O2 sensors didnt work. Got hom and found out they were not on the car. Somone cut off the pigtails/connectors from the harness and was running the rears only. The car has 1 7/8 headers, cam, cold air and all the supporting mods......supposedly. Big question is does any one have the color code pin placement for the pig tails. I found the 4 wires for each side taped off but dont know the pin placement for the new pigtails........any help would be appreciated.

codiath, the picture of the pigtail you posted is from the actual O2 sensor i believe. I need pics of the engine harness side. I also found the link you posted for the harness but cant find the same for the bank 2 sensor 1 side. Thanks for your help. If by chance you have pictures of your pig tails in the engine compartment bnak 1 sensor 1 and bank 2 sensor 1 from the back side where i can see the colors that would be a big help. Thanks again.

I hope you were able to get your issue all sorted out, but if not here is what I found using my car as reference. Bank 1 sensor 1 is driver side pre cat if I am correct, and bank 2 sensor 1 is passenger side pre cat. I might have missed a tracer but this should be enough info to get you wired up. I appears the only difference, side to side, is there is a grey wire in pin E on B1S1 and it is a green in pin E on B2S1.

Perfect, thanks you, your b2s1 wires are the same as mine but the b1s1 i have a light green/wh for pin e. Im hoping the difference in color code is the year, mine is a 2010.
