Black upstream is correct for the passenger side. So I think you're good now. Sorry for the confusion

Btw - when talking about connector colors, I'm only referring to the color of the connector on the sensor. I don't remember what colors the connectors are on the wire harness side, but those should be obvious based on location. The more forward/upward located harness connector is for the upstream sensor.

I'm thinking that Prodigy's instructions should be updated to not mention connector colors, and simply say to transfer the sensors from the stock pipes to the corresponding locations on the Prodigy pipes.
