Thanks for reply. Im fairly sure now the pigtail i bought from rock auto isnt correct and is causing the pins to not line up correctly when pluged in. Causing the emiss fuse to blow at least im hoping. Cause i followed the colors directly to the new pigtail and now its reading 0volts at the sensor. I have an oem one from a part out coming hopefully this fixes the problem. Thanks for the reply on the colors. So the pink one is where the 12v comes from?

k

looks like they are def not the same..i just assumed was different color cause aftermarket and tried to follow same colors on the old pig to new but it looks like doing so with the different connector ends is making the wires not match up to the 02 female correctly?? Fingers crossed
