So I'm sure I'm overthinking this but I just replaced my catalytic converters on my 2006 Ranger FX4 Level 2 with the 4.0 motor and I bought new O2 sensors for it. I wanted motorcraft sensors and none of the auto parts stores had motorcraft so bought them from rockauto. Banks 1 and 2 sensor 1 are fine and bank 2 sensor 2 is fine but sensor 2 for bank 1 is the wrong connector and looks exactly like the other sensor 2, but they have different part numbers. The part number on the one I'm thinking is wrong is f85f9g444ac (blue connector) and the part number on the old sensor is f85f9g444ea (green connector). Now the problem is the new one has the tabs on the connector in the wrong place and I can't find the right one. I've looked everywhere. I've searched the old part number and still no luck. I just can't seem to find the right sensor with the right connector for it. I've though about cutting the connectors off both of them and swapping them but I don't know what kind of effects that will cause. So any and all input is appreciated.

The biggest difference is the length of the pig tail. The one is longer. The reason the connectors are different is to keep them from getting crossed if they ever have to be disconnected at the same time (like if the trans has to come out). Having them crossed can cause a lot of running issues.

Just shave the tabs off the one that is wrong and be careful.

I called Ford today and the parts guy confirmed the one I bought is the right one for the truck and the f85f9g444ea should've never been on it. Which doesn't make sense because the truck has the pigtail for that sensor. Haven't had a chance to look and see if that pigtail on the truck was spliced there or not though. Decided earlier today to unpin and swap the connectors on my new and old sensors. Thank you for your feedback!
