Since I can't find any info on this maybe someone can help me out. I have an 02 WJ 4.0L and need to know which color connector goes to which downstream O2 sensor. I have a black connector and an off-white connector (engine harness side). Can someone maybe look at theirs and see which color connector goes to which downstream O2 - I have the four O2 sensor system (cali). Exhaust was out so the original attaching points weren't attached and harness doesn't really have "witness marks and/or bends". Just need to make sure.

TIA!
